I have created a paginatedList and pager for that for my ASP.NET MVC project. It works great, well thing so.
One thing that I cannot figure it out is to how to put ... after certain point. For example, lets say my pager looks like as follows :
1 2 3 4 5 6 7 8 9 10 11 12 13 14 Next >>>
What I need is some thing as follows :
1 2 3 4 5 6 7 8 9 10 ... Next >>>
the ... is for 11 here. When we go to page 11, the pager should be as follows :
... 11 12 13 14 Next >>>
This implementation is the one which I cannot figure it out how to do this.
And here is how my current pager code looks like :
<div id="pager">
#if (Model.PrimaryModel.HasPreviousPage) {
#:#Html.ActionLink(
"<<< Previous",
Model.Property["action"],
new {
controller = Model.Property["controller"],
Area = Model.Property["area"],
page = (Model.PrimaryModel.PageIndex - 1)
},
new {
data_jquery_ajax_url = Url.Action(
string.Format("pagerAjaxCall_{0}", Model.Property["action"]),
new {
controller = Model.Property["controller"],
Area = Model.Property["area"],
page = (Model.PrimaryModel.PageIndex - 1)
}
)
}
)
}
#if (Model.PrimaryModel.TotalPages >= 2) {
int totalPageNumber = 0;
for (int i = 0; i < Model.PrimaryModel.TotalPages; i++) {
int value = i + 1;
if (Model.PrimaryModel.PageIndex == i) {
#:#Html.ActionLink(value.ToString(), Model.Property["action"], new { controller = Model.Property["controller"], Area = Model.Property["area"], page = (i) }, new { #class = "active-page", data_jquery_ajax_url = Url.Action(string.Format("pagerAjaxCall_{0}", Model.Property["action"]), new { controller = Model.Property["controller"], Area = Model.Property["area"], page = (i) }) })
} else {
#:#Html.ActionLink(value.ToString(), Model.Property["action"], new { controller = Model.Property["controller"], Area = Model.Property["area"], page = (i) }, new { data_jquery_ajax_url = Url.Action(string.Format("pagerAjaxCall_{0}", Model.Property["action"]), new { controller = Model.Property["controller"], Area = Model.Property["area"], page = (i) }) })
}
totalPageNumber++;
}
#*#:current : #(Model.PrimaryModel.PageIndex+1), totalPage #totalPageNumber.ToString(), right side #((totalPageNumber - Model.PrimaryModel.PageIndex)-1), left side #(totalPageNumber - (totalPageNumber - Model.PrimaryModel.PageIndex))*#
}
#if (Model.PrimaryModel.HasNextPage) {
#:#Html.ActionLink(
"Next >>>",
Model.Property["action"],
new {
controller = Model.Property["controller"],
Area = Model.Property["area"],
page = (Model.PrimaryModel.PageIndex + 1)
},
new {
data_jquery_ajax_url = Url.Action(
string.Format("pagerAjaxCall_{0}", Model.Property["action"]),
new {
controller = Model.Property["controller"],
Area = Model.Property["area"],
page = (Model.PrimaryModel.PageIndex + 1)
}
)
}
)
}
</div>
Any thoughts?
Just should give you a general idea of how to fix it
var start = Model.PrimaryModel.PageIndex > 10 ? Model.PrimaryModel.PageIndex : 0;
if (start > 0) { //create "..." }
for (int i = start; i <= Model.PrimaryModel.TotalPages && i < start + 10; i++)
{
//generate pages
}
if (start + 10 < 0 Model.PrimaryModel.TotalPages) { //create "..." }

I am using XamForms.Controls.Calendar package for showing calendar in my project. I am marking events on the calendar using the below code.
private void AddSpecialDateWithList(List<events> list)
{
List<SpecialDate> newList = new List<SpecialDate>();
foreach (events model in list)
{
string startDate = model.start;
int startIndex = startDate.IndexOf('T');
if (startIndex > 0)
{
startDate = startDate.Substring(0, startIndex);
}
string endDate = model.end;
int endIndex = endDate.IndexOf('T');
if (endIndex > 0)
{
endDate = endDate.Substring(0, endIndex);
}
List<DateTime> dates = GetDatesBetween(DateTime.Parse(startDate), DateTime.Parse(endDate));
for(int i=0;i< dates.Count; i++)
{
var newDate = AddDate(dates[i], model);
newList.Add(newDate);
}
}
calendar.SpecialDates = newList;
}
private SpecialDate AddDate(DateTime dateTime, events model)
{
SpecialDate newDate = new SpecialDate(dateTime)
{
Selectable = true,
BackgroundPattern = new BackgroundPattern(1)
{
Pattern = new List<Pattern>
{
new Pattern { WidthPercent = 1f, HightPercent = 0.7f, Color = Color.White },
new Pattern{ WidthPercent = 1f, HightPercent = 0.3f, Color = Color.Yellow, Text = model.title, TextColor=Color.Black, TextSize=10, TextAlign=TextAlign.LeftCenter},
}
}
};
return newDate;
}

When I tap a day having event(31 Jan having maths homework), I need to get the event id and all the other details associated with that event. How can I do this feature? Also is it possible to show month, week and day view in XamForms.Controls.Calendar?
You could get the index of SpecialDate in your list in the event DateClicked
private void calendar_DateClicked(object sender, DateTimeEventArgs e)
{
int num = 0;
var specialList = calendar.SpecialDates;
var date = e.DateTime;
foreach(SpecialDate specialDate in specialList)
{
if(specialDate.Date.Year==date.Year&& specialDate.Date.Month == date.Month&&specialDate.Date.Day == date.Day)
{
events model = list[num];
// do something you want
}
else
{
num++;
}
}
}
Ok so I am trying to load a CSVStream into an ExcelPackage (I am using EPPlus).
It always fails at line 221482, no matter what option I choose. I am running on x64 and I have in my app.config...
The error given is the one from the title :(
public ExcelPackage ExcelPackageFromCsvStream(Stream csvStream)
{
var excelPackage = new ExcelPackage();
var workSheet = excelPackage.Workbook.Worksheets.Add("Sheet1");
var csvFormat = new ExcelTextFormat
{
Delimiter = ',',
TextQualifier = '"',
DataTypes = new[] { eDataTypes.String }
};
using (var sr = new StreamReader(csvStream))
{
int i = 1;
foreach (var line in sr.ReadLines("\r\n"))
{
workSheet.Cells["A" + i].LoadFromText(line, csvFormat);
i++;
}
}
return excelPackage;
}
Resolved it by creating multiple ExcelPackages and also I've read the stream in batches (e.g. 200k lines at once)
public List<ExcelPackage> ExcelPackagesFromCsvStream(Stream csvStream, int batchSize)
{
var excelPackages = new List<ExcelPackage>();
int currentPackage = -1; // so that first package will have the index 0
var csvFormat = new ExcelTextFormat
{
Delimiter = ',',
TextQualifier = '"',
DataTypes = new[] {eDataTypes.String}
};
using (var sr = new StreamReader(csvStream))
{
int index = 1;
foreach (var line in sr.ReadLines("\r\n"))
{
if ((index - 1) % batchSize == 0)
{
var excelPackage = new ExcelPackage();
excelPackage.Workbook.Worksheets.Add("Sheet1");
excelPackages.Add(excelPackage);
currentPackage++;
index = 1;
}
excelPackages[currentPackage].Workbook.Worksheets.First().Cells["A" + index].LoadFromText(line, csvFormat);
index++;
}
}
return excelPackages;
}
I am trying to figure find why my api is taking ~5 secs working on 1000 records,is that good or bad?I want to know what tools are there in asp.net webapi to figure out which piece of code or where its consuming time and fine tune the performance

I am using the Extjs4 multigrouping plugin from here.
I have used it successfully, however i want to show the summary of the totals of each column within the group header itself . how do i set up the appropriate CSS for that ?
In Multigrouping.js
getFragmentTpl: function() {
var me = this;
return {
indentByDepth: me.indentByDepth,
depthToIndent: me.depthToIndent,
renderGroupHeaderTpl: function(values, parent) {
return Ext.XTemplate.getTpl(me, 'groupHeaderTpl').apply(values, parent);
//var z = new Ext.XTemplate('{name} ({rows.grouplength})');
//return z.apply(values, parent);
}
};
},
In my grid
features: [
{
ftype:'multigrouping',
groupHeaderTpl: [
'{[this.readOut(values)]}',
{
readOut:function(values) {
debugger;
var sum1 =0 ,sum2=0,sum3=0;
for( var i = 0 ; i< values.records.length ; i++)
{
var val = parseFloat(values.records[i].data.d2012.mp);
sum1 += isNaN(val) ? 0.0 : val;
val = parseFloat(values.records[i].data.d2013.mp);
sum2 += isNaN(val) ? 0.0 : val;
val = parseFloat(values.records[i].data.d2014.mp);
sum3 += isNaN(val) ? 0.0 : val;
}
return values.name + '(' + values.records.length + ')' + ' ' + sum1.toFixed(2) + ' ' + sum2.toFixed(2) + ' ' + sum3.toFixed(2);
}
}
]
},
had to resort to a few hacks to get this to work. still waiting on an official answer.
The main reason i had to do this and not use the multigrouping summary is because
- i want to limit the number of records from the server. I can do some smart grouping of
my business objects at the server side.
- the main reason to do this is because of IE8's performance on larger sets of data.
- had already tried the extjs4 tree grid component which works well on chrome but had performance issues on IE8.
the hack is to
a) use an array property in the grid to store the dom elements which i want to manipulate
b) use a boolean to know when the layout is completed the first time
b) add listeners for afterlayout ( when your app can do an Ext.get('..dom element..') you know you are done )
The listener :
listeners :
{
afterlayout : function(eopts)
{
var x = this.mOwnArray;
if(!this.loadedwithVals && x.length > 0)
{
for(var i =0 ; i<x.length ; i++)
{
var dom = Ext.get(x[i].id);
var theId = dom.id;
theId = theId.match(/\d+/)[0];
var title = dom.query("td[class='x-grid-cell x-grid-cell-first']");
title[0].className = 'x-grid-cell x-grid-cell-gridcolumn-' + theId + ' x-grid-cell-first';
title[0].colSpan=1;
var groupedHeader = dom.query("div[class='x-grid-group-title']");
groupedHeader[0].innerHTML = x[i].name + '(' + x[i].length + ')';
for(var year=2012;year<=2018;year++)
{
var t = "t"+year;
var someText1 = '<td class=" x-grid-cell x-grid-cell-numbercolumn">';
var someText2 = '<div class="x-grid-cell-inner " style="text-align: left; ;">';
var someText3 = '<div class="x-grid-group-title">' + x[i].total[t] + '</div></div></td>';
var someText = someText1 + someText2 + someText3;
dom.insertHtml("beforeEnd",someText);
}
}
this.loadedwithVals = true;
}
}
And the feature as in

{
ftype:'multigrouping',
startCollapsed : true,

readOut:function(values) {

for(var year=2012;year<=2018;year++)

var d = "d"+year;
var ct = "t" + year;
var arecord = values.records[i].data;
var val = parseFloat(arecord[d].mp);
val = isNaN(val) ? 0.0 : val;
Ext.Array.push(header.total[ct],val);
}
}
// push the sum of the records into its top level group
for(var year = 2012 ; year <= 2018 ; year++)

var sum = Ext.Array.sum(header.total[t]);
header.total[t] = sum.toFixed(2);
}
header.name = values.name;

hey guys,
i have a gridview which displays 10records per page, now i want to implement shift+click option in my gridview, when user clicks on the first row and press shift key and click on the 5th row, all the rows between 1 and 5(1 and 5 inclusive) should be selected...
can anyone suggest how should i do this in javascript.
I take it back, I found a shift+click multiple select solution for a gridview. All credit goes to mdv over at the asp forums.
var _sPreviousRow = null;
function wsCheckRange(p_oGridView, p_oControl, e) {
var l_sCheckID = p_oControl.id;
var l_aCheckIDParts = l_sCheckID.split(p_oGridView.id);
var l_sCurrentRow = l_aCheckIDParts[1].split('_')[1].substring(3);
var l_oEvent = (window.event) ? event : e;
if (l_oEvent.shiftKey) {
if (_sPreviousRow != null && _sPreviousRow != l_sCurrentRow) {
var l_iFirst = 0, l_iLast = 0;
if (parseInt(_sPreviousRow,10) > parseInt(l_sCurrentRow,10)) {
l_iFirst = parseInt(l_sCurrentRow,10);
l_iLast = parseInt(_sPreviousRow,10);
}
else {
l_iFirst = parseInt(_sPreviousRow,10);
l_iLast = parseInt(l_sCurrentRow,10);
}
for (var i = l_iFirst; i < l_iLast; i++) {
var l_sLastRow = (i <= 9 ? '0' + i : i);
var l_sCtrlNew = l_sCheckID.replace('ctl' + l_sCurrentRow, 'ctl' + l_sLastRow);
var l_oCtrlNew = $get(l_sCtrlNew);
if (l_oCtrlNew) {
l_oCtrlNew.checked = p_oControl.checked;
}
}
}
_sPreviousRow = null;
}
else {
_sPreviousRow = l_sCurrentRow;
}
}
