I have this code which works fine as long as as dt.Value is different to "int".
This is the line which errors:
(dt.Value.ToLower().Substring(0, 4).Equals("date"))
It works fine if dt.Value is varchar or datetime.
I provided my suggested solution at the end of this post.
// Edit
if (e.CommandName == "Edit")
{
// Get the item
RepeaterItem Item = ((RepeaterItem)((Button)e.CommandSource).NamingContainer);
// Get buttons and repeater
Button savebtn = (Button)(Item.FindControl("btnSave"));
Button editbtn = (Button)(Item.FindControl("btnEdit"));
Repeater rFields = (Repeater)(Item.FindControl("repFields"));
// Enable my fields
foreach (RepeaterItem RI in rFields.Items)
{
// Get data type
HiddenField dt = (HiddenField)(RI.FindControl("hdnDBDataType"));
// Set controls
if (RI.FindControl("chkSetting").Visible) ((CheckBox)RI.FindControl("chkSetting")).Enabled = true;
if (RI.FindControl("ddlSetting").Visible) ((DropDownList)RI.FindControl("ddlSetting")).Enabled = true;
if (RI.FindControl("txtSetting").Visible)
{
((TextBox)RI.FindControl("txtSetting")).Enabled = true;
// Check my data type
if (dt.Value.ToLower().Substring(0, 4).Equals("date")) ((CalendarExtender)RI.FindControl("extDateTime")).Enabled = true;
}
}
}
Is this a good fix ? TIA
if(dt.Value != "int" && dt.Value.ToLower().Substring(0, 4).Equals("date"))
Substring will throw an error if the second parameter is higher than the lenght of the string. What you need to do is check the length before doing the substring or use a method like #Igor suggested in the comments.
Your suggestion to check != "int" is not fullproof if let's say somehow the value is any string less than 4 characters.
(dt.Value.Length > 3 && dt.Value.ToLower().Substring(0, 4).Equals("date"))
I will also put #Igor suggestion here because it is also fullproof:
(dt.Value.StartsWith("date", StringComparison.OrdinalIgnoreCase)
I am trying to have my Flexicious DataGrid ask for confirmation of a change when I click in a cell to edit a value and enter a new value which deviates from the original by a certain percentage. I cannot see an easy way to do this. Initially, I tried to write a itemEditorValidatorFunction, which returns a boolean. This works perfectly for a hard coded return value, but if I try to take the return value from the CloseEvent of an Alert, that value is ignored:
protected function validateGcCap(editor:UIComponent):Boolean{
var warningBPDiffVal:Number = Number(5);
var warningPerCentDiffVal:Number = Number(warningBPDiffVal / 1000);
var allowChange:Boolean = true;
var origGcCapVal:Number = Number(managerGrid.getCurrentEditingCell().text);
var newGcCapVal:Number = Number((editor as TextInput).text);
var diffVal:Number = Number(newGcCapVal - origGcCapVal);
if (origGcCapVal > newGcCapVal) {
diffVal = origGcCapVal - newGcCapVal;
}
if (diffVal > warningPerCentDiffVal) {
//Alert.show("you changed the gccap from " + origGcCapVal + " to " + newGcCapVal + " by " + diffVal);
function alertCloseHandler(event:CloseEvent):void{
if (event.detail == Alert.CANCEL) {
allowChange = false;
}
};
var alert:Alert = Alert.show("Are you sure that you want to update gcCap% by more than " + warningBPDiffVal + "bps?",
"Please Confirm", (Alert.OK | Alert.CANCEL),
this, alertCloseHandler);
}
return allowChange;
}
I also tried to write a itemEditor for the grids:FlexDataGridColumn, where I extended com.flexicious.controls.TextInput, but I could not work out which method to override. I wanted to override the method and only make the call to super if the Alert was clicked OK, but I could not see which method I should override. I tried override protected function onTextInput(textEvent:TextEvent):void, but this did nothing.
I would be grateful for any insight into this problem.
Not sure why someone decided to downvote your question, it seems quite valid. From looking at this, the best way for you would be to "undo" the edit when the user selects no on the box. If you have enableTrackChanges on, all you have to do is to remove that change from the dgGrid.changes collection and call dgGrid.refreshCells(). If you dont have enableTrackChanges, all you need to do is to update the dataProvider row with the old value, call dgGrid.refreshCells() and you should be set.
This is what works:
private function validateGcCap(editor:UIComponent):Boolean{
var warningBPDiffVal:Number = Number(5);
var cell:IFlexDataGridCell = managerGrid.getCurrentEditingCell();
var warningPerCentDiffVal:Number = Number(warningBPDiffVal / 1000);
var origGcCapVal:Number = Number(cell.text);
var newGcCapVal:Number = Number((editor as TextInput).text);
var diffVal:Number = Number(newGcCapVal - origGcCapVal);
if (origGcCapVal > newGcCapVal){
diffVal = origGcCapVal - newGcCapVal;
}
if (diffVal > warningPerCentDiffVal){
function alertCloseHandler(event:CloseEvent):void{
if (event.detail == Alert.CANCEL) {
IAParamsVO(cell.rowInfo.data).gcCapWrapper = origGcCapVal;
managerGrid.refreshCells();
}
}
Alert.show("Are you sure that you want to update gcCap% by more than "
+ warningBPDiffVal + "bps?", "Please Confirm", (Alert.OK | Alert.CANCEL),
this, alertCloseHandler);
}
return true;
}
I tried group telerik grid using drop down list
grouping method source code is bellow
try
{
this.grd.MasterTableView.GroupByExpressions.Clear();//clear all group expressions
grd.MasterTableView.GroupsDefaultExpanded = false;
GridGroupByExpression expression = new GridGroupByExpression();
GridGroupByField gridGroupByField = new GridGroupByField();
gridGroupByField = new GridGroupByField();
if (cboGroupByItem1.SelectedValue != "0")
{
gridGroupByField.FieldName = cboGroupByItem1.SelectedValue;
gridGroupByField.HeaderText = cboGroupByItem1.SelectedItem.Text;
expression.SelectFields.Add(gridGroupByField);
}
if (cboGroupByItem2.SelectedValue != "0")
{
gridGroupByField.FieldName = cboGroupByItem2.SelectedValue;
gridGroupByField.HeaderText = cboGroupByItem2.SelectedItem.Text;
expression.SelectFields.Add(gridGroupByField);
}
grd.MasterTableView.GroupByExpressions.Add(expression);
}
catch (Exception ex)
{
label1.Text = ex.ToString();
}
finally
{
grd.Rebind();
}
when grid rebind method it will generate bellow error
An error occurred adding a relation to DataRelationCollection. Please,
make sure you have configured the expressions properly - both
GroupByFields and SelectFields are required!
How to solve this problem ?
You need to add this line after you add the gridGroupField to expression.
expression.GroupByFields.Add(gridGroupByField);
As the error message says, you need to add the fields you want to groupby.
If you have an aggregate field you dont have to add it to the expression as GroupByField, only as SelectFields.
Hope it helps.
I'm trying to implement this solution to "grey out" past events in Fullcalendar, but I'm not having any luck. I'm not too well versed in Javascript, though, so I assume I'm making some dumb mistakes.
I've been putting the suggested code into fullcalendar.js, inside the call for daySegHTML(segs) around line 4587.
I added the first two lines at the end of the function's initial var list (Why not, I figured)—so something like this:
...
var leftCol;
var rightCol;
var left;
var right;
var skinCss;
var hoy = new Date;// get today's date
hoy = parseInt((hoy.getTime()) / 1000); //get today date in unix
var html = '';
...
Then, just below, I added the other two lines inside the loop:
for (i=0; i<segCnt; i++) {
seg = segs[i];
event = seg.event;
classes = ['fc-event', 'fc-event-skin', 'fc-event-hori'];
if (isEventDraggable(event)) {
classes.push('fc-event-draggable');
}
unixevent = parseInt((event.end.getTime()) / 1000); //event date in Unix
if (unixevent < hoy) {classes.push('fc-past');} //add class if event is old
if (rtl) {
if (seg.isStart) {
classes.push('fc-corner-right');
}
...
Running this code results in a rendered calendar with no events displayed and an error message: Uncaught TypeError: Cannot call method 'getTime' of null
The "null" being referred to is, apparently, event.end.getTime(). But I'm not sure I understand what exactly is going wrong, or how things are being executed. As written, it seems like it should work. At this point in the code, from what I can tell, event.end contains a valid IETF timecode, but for some reason it's "not there" when I try to run it through getTime()?
This isn't a mission-critical tweak for me, but would still be nice—and I'd like to understand what's going on and what I'm doing wrong, as well! Any help greatly appreciated!
If you are using FullCalendar2 with Google Calendar, you will need to use the version of the code below. This uses Moment.js to do some conversions, but since FC2 requires it, you'll be using it already.
eventRender: function(event, element, view) {
var ntoday = new Date().getTime();
var eventEnd = moment( event.end ).valueOf();
var eventStart = moment( event.start ).valueOf();
if (!event.end){
if (eventStart < ntoday){
element.addClass("past-event");
element.children().addClass("past-event");
}
} else {
if (eventEnd < ntoday){
element.addClass("past-event");
element.children().addClass("past-event");
}
}
}
As per FullCalendar v1.6.4
Style past events in css:
.fc-past{background-color:red;}
Style future events in css:
.fc-future{background-color:red;}
There's no need to fiddle with fullcalendar.js. Just add a callback, like:
eventRender: function(calev, elt, view) {
if (calev.end.getTime() < sometime())
elt.addClass("greyclass");
},
you just have to define the correct CSS for .greyclass.
Every event has an ID associated with it. It is a good idea to maintain your own meta information on all events based on their ids. If you are getting the events popupated from a backend database, add a field to your table. What has worked best for me is to rely on callbacks only to get the event ids and then set/reset attributes fetched from my own data store. Just to give you some perspective, I am pasting below a section of my code snippet. The key is to target the EventDAO class for all your needs.
public class EventDAO
{
//change the connection string as per your database connection.
//private static string connectionString = "Data Source=ASHIT\\SQLEXPRESS;Initial Catalog=amit;Integrated Security=True";
//this method retrieves all events within range start-end
public static List<CalendarEvent> getEvents(DateTime start, DateTime end, long nParlorID)
{
List<CalendarEvent> events = new List<CalendarEvent>();
// your data access class instance
clsAppointments objAppts = new clsAppointments();
DataTable dt = objAppts.SelectAll( start, end);
for(int i=0; i<dt.Rows.Count; ++i)
{
CalendarEvent cevent = new CalendarEvent();
cevent.id = (int)Convert.ToInt64(dt.Rows[i]["ID"]);
.....
Int32 apptDuration = objAppts.GetDuration(); // minutes
string staffName = objAppts.GetStaffName();
string eventDesc = objAppts.GetServiceName();
cevent.title = eventDesc + ":" + staffName;
cevent.description = "Staff name: " + staffName + ", Description: " + eventDesc;
cevent.start = (DateTime)dt.Rows[i]["AppointmentDate"];
cevent.end = (DateTime) cevent.start.AddMinutes(apptDuration);
// set appropriate classNames based on whatever parameters you have.
if (cevent.start < DateTime.Now)
{
cevent.className = "pastEventsClass";
}
.....
events.Add(cevent);
}
}
}
The high level steps are as follows:
Add a property to your cevent class. Call it className or anything else you desire.
Fill it out in EventDAO class while getting all events. Use database or any other local store you maintain to get the meta information.
In your jsonresponse.ashx, retrieve the className and add it to the event returned.
Example snippet from jsonresponse.ashx:
return "{" +
"id: '" + cevent.id + "'," +
"title: '" + HttpContext.Current.Server.HtmlEncode(cevent.title) + "'," +
"start: " + ConvertToTimestamp(cevent.start).ToString() + "," +
"end: " + ConvertToTimestamp(cevent.end).ToString() + "," +
"allDay:" + allDay + "," +
"className: '" + cevent.className + "'," +
"description: '" +
HttpContext.Current.Server.HtmlEncode(cevent.description) + "'" + "},";
Adapted from #MaxD The below code is what i used for colouring past events grey.
JS for fullcalendar pulling in Json
events: '/json-feed.php',
eventRender: function(event,element,view) {
if (event.end < new Date().getTime())
element.addClass("past-event");
},
other options ....
'event.end' in my Json is a full date time '2017-10-10 10:00:00'
CSS
.past-event.fc-event, .past-event .fc-event-dot {
background: #a7a7a7;
border-color: #848484
}
eventDataTransform = (eventData) => {
let newDate = new Date();
if(new Date(newDate.setHours(0, 0, 0, 0)).getTime() > eventData.start.getTime()){
eventData.color = "grey";
}else{
eventData.color = "blue";
}
return eventData;
}
//color will change background color of event
//textColor to change the text color
Adapted from #Jeff original answer just simply check to see if an end date exists, if it does use it otherwise use the start date. There is an allDay key (true/false) but non allDay events can still be created without an end date so it will still throw an null error. Below code has worked for me.
eventRender: function(calev, elt, view) {
var ntoday = new Date().getTime();
if (!calev.end){
if (calev.start.getTime() < ntoday){
elt.addClass("past");
elt.children().addClass("past");
}
} else {
if (calev.end.getTime() < ntoday){
elt.addClass("past");
elt.children().addClass("past");
}
}
}
Ok, so here's what I've got now, that's working (kind of):
eventRender: function(calev, elt, view) {
var ntoday = new Date();
if (calev.start.getTime() < ntoday.getTime()){
elt.addClass("past");
elt.children().addClass("past");
}
}
In my stylesheet, I found I needed to restyle the outer and inner elements to change the color; thus the elt.children().addclass addition.
The only time check I could get to work, lacking an end time for all day events, was to look at the start time - but this is going to cause problems with multi-day events, obviously.
Is there another possible solution?
I have two labels and two text boxes, a Compare validator and a button.
I need it to compare two dates (rental date , return date ) and when the rental date is less or equal to return date are the same. No validation message.
While when when the rental date is less than the return date, display an input error message.
The compare validator has been set with :
controltocompare : txtrental,
controltovalidate: txtreturndate,
operator :greater than equal,
type:date,
errormessage: return date must be greater or equal than rental date,
I am not sure how to get the btn to display it ?
You need to set the property "CausesValidation" of your button to "true" to trigger validation on its click.
Make sure the CompareValidator has runat="server"
Create a method to display message.
private void AlertBox(string Msg)
{
string s = "alert('" + Msg + "')";
ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "ckey", s, true);
}
find the code to validate and throw alert message.
if (!String.IsNullOrEmpty(txtrental.Text) && !String.IsNullOrEmpty(txtreturndate.Text))
{
DateTime ssSD = Convert.ToDateTime(txtrental.Text);
DateTime qsED = Convert.ToDateTime(txtreturndate.Text);
int chktxtfd1_sd = ssSD.CompareTo(qsSD);
if ((chktxtfd1_sd == 0 || chktxtfd1_sd == -1) )
{
//do something bcoz condition is true
}
else
{
lvflag = false;
AlertBox("date must be greater or equal than rental date");
}
}
