Save changes in editable data grid with enter key - xpages - datagrid

I have a data grid that displays on my xPage. I allow the user to edit two of the fields in the grid. I would like either field to recognize the user hitting the enter key and automatically save those line changes to its document. I don't want to use a button for the user to manually click. Can someone explain how I can do that with a code snippet? Thanks.

Mike,
In your edit fields, you can have code like this. Note that keyCode #13 is the enter key. You can find out the keycode of specific keyboard keys using http://keycode.info/
You would likely want to execute serverside code to save your document. I haven't every tried using the keycode in SSJS, so I can't say it works for sure. But the keypress event is the way to go for what you are trying to accomplish.
var keyCode = event.keyCode;
if(keyCode == 13){
//Save here
}else{
event.returnValue = false;
}
If the UI doesn't make it easy to add the keypress event, you can still add it to the source. It has to be on an editable input field to work.
<xp:eventHandler event="onkeypress" submit="true" id="eventHandler1" refreshMode="partial">
<xp:this.action><![CDATA[#{javascript:var keyCode = event.keyCode;
if(keyCode == 13){
//Save here
}else{
event.returnValue = false;
}}]]></xp:this.action>
</xp:eventHandler>

bootstrap studio: enter key appears to causing reload of page

I have a web page with several forms. Only one is visible at a time, depending on state.
On one form, pressing the enter key appears to be causing a reload of the page rather than triggering a click event for the form's button.
I have a lot of javascript, primarily because I need client side interaction with mailchimp. Because of that, I have disabled the form's action= html and have instead created a javascript function to handle the click. It works fine if you click on the button.
I have also assigned a listener for the sole field in the form:
var input = document.getElementById ("new-email-address");
input.addEventListener ("keyup", function(event)
{
if (event.keyCode === 13)
{
event.preventDefault();
document.getElementById("new-email-address").click();
}
});
Yet, when I click the enter key, the $(document).ready (function() executes. It's possible something else is executing beforehand, but, if so, I haven't found a way to discover that.
What could be causing this behavior ?
It turns out that the enter key is being handled at the form level. To disable that, I added this code for each form:
$("#the-form").keypress(function(e)
{
if (e.which == 13) // Enter key
return false;
});

Disable asp:Textbox editing when an other textbox is filled in real time

I have two TextBoxes, and I want to prevent the user from editing one of it while the other is not empty in real time. How could I do that ?
You can add a text changed event on the textbox that needs a input firts. Then in you C# side you can do a check in that event to see:
If(string.IsNullOrEmpty(txtbox.Text))
{
txtbox2.Enabled = false
}
else
{
txtbox2.Enabled = true;
}
Hope that helps
The interaction you're describing is on the client, not the server, so you'll need to write some javascript to make that happen.
Add this to the bottom of your aspx page. Depending on the id schema you're solution is using, you may need to inspect the Id's of the textareas in your browser to get their actual DOM element Id's. (note - haven't tested the code, but you get the idea)
<script>
var elDisabledTxtBx = document.getElementById("Your_Disabled_Textbox_ID");
var elTxtbxThatAcceptsInput = document.getElementById("ID_of_textbox_user_types_into");
$(elTxtbxThatAcceptsInput).on("keyup", function(el, $e){
if ( this.value.trim() === "" ){
elDisabledTxtBx.disabled = false;
}
});
</script>

Proper validation is ASP.net

i have a field ProductID and another field ProductName.I would like a validation where if product ID is entered and product type is not selected it should alert user to select product Name (combo box) on the submit button click.
What will be the appropriate way to do it? I do not wish to write any script hence cannot use custom validator.
how else can i write it?
i am using ASP.NET C#.
Thanks
You can use jQuery to do this very easily. Just wire a click event handler on your submit button. Take a look at this fiddle -
http://jsfiddle.net/8efopLff/1/
JQuery code
$("#btn").click(function(){
if($("#field1").val() != "" && $("#field2").val() == "")
{
alert("Please select field 2");
}
return false;
});

Anguilla - Updating a field's value from a popup?

I have a modal popup that appears whenever an editor tries to save a component with some values (a date field in the past in this case).
In this popup I show the editor a few options (very similar to the default "Open Shared Item" dialog) and an OK/Cancel button combo. On Cancel I fire the "cancel" event and the editor goes back to the editing screen, all good here. On "OK" I want to change the value of the field to match whatever the editor selected, then save.
I tried to use an approach with FieldBuilder and the sample Boris mentioned on this other topic but I can't get to the field from my popup dialog.
Any suggestions on how I can go and modify the xml of the item (could be also a page) from a modal popup?
EDIT: Code used in getControlForFieldName
function getControlForFieldName(name) {
var fieldBuilder = $display.getView().properties.controls.fieldBuilder;
var fieldsContainer = fieldBuilder.properties.input;
var fieldsNode = fieldsContainer.getElement();
var fieldContainer = $dom.getFirstElementChild(fieldsNode);
while (fieldContainer) {
var labelNode = $dom.getFirstElementChild(fieldContainer);
var fieldNode = $dom.getNextElementSibling(labelNode);
var control = fieldNode.control;
if (control.getFieldName() == name) {
return control;
}
fieldContainer = $dom.getNextElementSibling(fieldContainer);
}
}
EDIT #2
After Frank's advice, and some help from Jaime & Frank offline, I got it to work as follows:
The popup is called from a Command Extension (Save & Close in my case)
The command.js specifies an event handler that gets called on "submit" (== OK was pressed)
$evt.addEventHandler(p.dialogPopup, "submit",
this.getDelegate(this._onPopupSubmit));
In my popup I am passing the selected item (it's a keyword ID) to the event handler:
this.fireEvent("submit", { id: select.options[select.selectedIndex].value });
and now back in the event handler _onPopupSubmit(e) I just read e.data.id, load this keyword, get properties like ID & Title, and update the metadata of the item using item.setMetadata("new metadata with updated values").
Simple :)
Your code runs in a popup, so any references you make to global variables will be taken from the popup window.
So when you get the fieldBuilder:
var fieldBuilder = $display.getView().properties.controls.fieldBuilder;
$display is a reference to a global variable. So this actually looks for the FieldBuilder in the popup window (which doesn't have one).
To get the FieldBuilder of the Component window, you can get it from the opener:
var fieldBuilder = opener.$display.getView().properties.controls.fieldBuilder;
You might want to consider actually passing the updated value to either a callback function or with a (custom) event though, since that makes your popup less dependent on opener. trick.

How does one cancel/unaccept a drag-and-drop operation in Flex 3?

Goal:
Allow the user to delete a record by dragging a row from an AdvancedDataGrid, dropping it onto a trash-can icon and verify the user meant to do that via a popup alert with "OK" and "Cancel" buttons.
What is working:
Dragging/Dropping a row onto the trash icon.
If the user clicks the "OK" button, the record is deleted.
If the user clicks the "Cancel" button, the operation is canceled.
Problem:
After the user clicks the "Cancel" button and the popup alert closes, no rows in the ADG can be dragged. I've discovered that after sorting the ADG, by clicking on a column header, the user can begin dragging rows again.
Code: (changed from original post)
<mx:Image source="{trashImage}" buttonMode="true"
toolTip="drag a participant here to delete them from the project"
dragDrop="deleteParticipantDrop(event)" dragEnter="deleteParticipantEnter(event)"
dragExit="deleteParticipantDragExit(event)" top="4" right="122" id="image2" />
// trashImage Event Handlers:
private function deleteParticipantEnter(event:DragEvent):void
{
var component:IUIComponent = IUIComponent(event.currentTarget);
dragComponent = component;
DragManager.acceptDragDrop(component);
DragManager.showFeedback(DragManager.MOVE);
deleteParticipantDragEvent = event;
}
private function deleteParticipantDrop(event:DragEvent):void
{
var selectedKitNum:String = memberRpt.selectedItem.KitNum;
var selectedName:String = memberRpt.selectedItem.ParticipantName;
var component:IUIComponent = IUIComponent(event.currentTarget);
dragComponent = component;
DragManager.acceptDragDrop(component);
isEditingParticipantInfo = false;
isDeletingParticipant = true;
deleteParticipantDropEvent = event;
event.stopImmediatePropagation(); // Added as per mrm
alert.confirm("Are you sure you want to delete this participant, Kit #" + memberRpt.selectedItem.KitNum + " (" +
memberRpt.selectedItem.ParticipantName + ") from the project? This cannot be reversed!! An email will be " +
"sent to notify this participant and you will receive a copy of it for your records.", confirmRemoveParticipant);
}
private function deleteParticipantDragExit(event:DragEvent):void
{
var component:IUIComponent = IUIComponent(event.currentTarget);
dragComponent = component;
DragManager.acceptDragDrop(component);
DragManager.showFeedback(DragManager.NONE);
}
private function confirmRemoveParticipant(event:CloseEvent):void
{
if (event.detail == Alert.YES)
{
deleteReason = DeleteParticipantTitleWindow(PopUpManager.createPopUp( this, DeleteParticipantTitleWindow , true));
dispatchEvent(deleteParticipantDropEvent); // Added as per mrm
PopUpManager.centerPopUp(deleteReason);
deleteReason.showCloseButton = true;
deleteReason.title = "Reason for removal from project";
deleteReason.addEventListener("close", cleanupRemoveParticipant);
deleteReason["cancelButton"].addEventListener("click", cleanupRemoveParticipant);
deleteReason["okButton"].addEventListener("click", finalizeDeleteParticipant);
isDeletingParticipant = false;
}
else
{
cleanupRemoveParticipant();
}
}
private function cleanupRemoveParticipant(event:Event = null):void
{
memberRpt.invalidateDisplayList();
memberRpt.executeBindings();
if (deleteReason != null)
{
PopUpManager.removePopUp(deleteReason);
deleteReason = null;
}
}
public function finalizeDeleteParticipant(event:Event):void
{
if (deleteReason.reason.text != null)
{
selectedReportItem = memberRpt.selectedItem;
selectedReportItemIndex = memberRpt.selectedIndex;
memberReportData.removeItemAt(selectedReportItemIndex);
}
else
{
alert.info("You must provide a reason for removing a participant from your project!!");
}
cleanupRemoveParticipant();
}
Thanks in advance for all helpful suggestions.
Have you tried running the validateNow() method on the ADG after the cancel event?
Here is some more information on the validateNow() method.
Why you need to know about validateNow...
I really do think this is what you're looking for! Please let us know if that is the case...
Try refreshing the data bindings on the datagrid using executeBindings and/or invalidateDisplayList in the enclosing control.
To be honest this sounds a bit like a bug. Have you posted this on flexcoders? The Adobe guys hang out on there (probably here too, but definitely there)
Hang on... just spotted that between the drop event and the cancel button of the popup there is an asynchronous web service call which appears to be handled by GetParticipantOrderInformation. Is that correct?
If yes, then have you tried offering a simpler dialog for Cancel before you do that? I wonder whether the combination of layers of events is causing a problem.
I didn't have any success with refreshing the data bindings on the datagrid via the executeBindings and invalidateDisplayList methods. I also didn't have any luck by showing the confirmation alert before making the webservice call. In fact, I discovered that making the webservice call was completely unnecessary and removed it. So now the code flows like this:
Drag/drop ADG row onto trash icon.
Display confirmation Alert box.
If user clicked "Cancel" button, redisplay the ADG.
But the same problem persists. I'll update the Code section with the latest code.
Here's an idea:
- Just before you create the alert window, stop the DragEvent
event.stopImmediatePropagation();
store the event so we can resume if the user clicks the Yes button
queuedEvent = event as DragEvent;
show the alert window
if the user clicks the yes button, resume the queued event
dispatchEvent(queuedEvent);
DragManager.showFeedback(DragManager.NONE);
