Dirty Check with RadComboBox and DatePicker

Hi,

Requirement:
if any value of control change a flaf "dirty" is set to true else it is false. When user leave that page and if dirty flag is true. He is asked to save records or close window without saving.

We are using below script to find dirty flag for all the controls.

<script>
 
 
    var isDirty = false;
    var resetControls = ""; // should be in , separated with # in ids
	var msg = 'You haven\'t saved your changes.\n Do you want to save changes ?';
 
 
 
 
	$(document).ready(function () {
	    alert($(".section :hidden").length);
	    
	    $(":submit,:reset ").click(function () {
	        isDirty = false;
	        alert("Dirty flag reset");
	    });
	    $(':input').change(function () {
	        if (!isDirty) {
	            alert("Dirty flag set")
	            isDirty = true;
	        }
	    });
 
	    window.onbeforeunload = function () {
	        if (isDirty) {
	            return msg;
	        }
	    };
 
	});
 
 
</script>

Above script is working fine with all input controls except hidden fields. Specifically RadComboBox and RadDatePicker are using hidden fields to post data.

Could you please provide solution so that we can check dirty flag with rad controls ?

Build menu from codebehind

Hello,

I need to render a RadMenu from code behind; I would like to do simply calling a sub (will be responsible to generate the menu) but I did not find anything similar around.
The call will be something like:
BuildMenu()

This sub will do the following:

Define the root menu and build the submenu for each root.

How can I acheive this?
Thanks

How would that be possible to overwrite the PdfExport functionality?

I'd need to display an Export to Pdf icon to the RadGrid control (CommandItemSettings.ShowExportToPdfButton = true) but with a custom implementation of my own as I'm using an external tool for the export to pdf.

How would that be possible to overwrite the default PdfExport functionality?

Please advise.

Many thanks,

ItemCommand does not fire

I'm going crazy and I'm not sure what the problem is.

Here is my situation:
My main page (aspx) contains two usercontrol (ascx)
first one is basically a tree. second one is a radgrid and some textbox I fill on row selection itemcommand.

The second one is dinamically loaded depending on tree's node value has a radgrid. I mean, I load different ascx by the node's value but they all are a radgrid and textboxes.

main Page

<td>

<qsf:RTV runat="server" ID="CatTree1" ></qsf:RTV>

</td>

<td style="width:80%;vertical-align:top">

<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<asp:PlaceHolder ID="PlaceHolder_UC" runat="server"></asp:PlaceHolder>

</ContentTemplate>

<Triggers>

<asp:AsyncPostBackTrigger ControlID="CatTree1" />

</Triggers>

</asp:UpdatePanel>

</td>

PlaceHolder_UC is dinamically loaded this way

function AAAAAAA()....

Dim UControl As Control

If ....

controlPath = "Arrangements2.ascx"

End If

UControl = CType(LoadControl(controlPath), UserControl)

If controlPath <> "" Then

If Not (UControl Is Nothing) Then

'ascx dinamically attached

PlaceHolder_UC.Controls.Clear()

PlaceHolder_UC.Controls.Add(UControl)

.....

Dim myUC As ASP.Arrangements2 = DirectCast(tempControl, ASP.Arrangements2)

'here I Call function on second ascx, fill radgrid whit data

myUC.InitControl(value)

....

End If

I call AAAAAAA on the nodeclick event catch on the aspx raised by my first ascx
Ascx2 radgrid is filled, i click on the rows, itemcommand fires, I fill the textboxes. everything is ok

here come my problem
I click on a different tree's node, AAAAAAA is called, ascx2 radgrid is filled with a new set of data, i click on the rows and itemcommand never fires

here's my ascx2 (summaring)

<asp:UpdatePanel ID="UpdatePanelAscx" runat="server" UpdateMode="Conditional">

<ContentTemplate>

<telerik:RadGrid ID="RadGridArrangement"

runat="server"

OnItemCommand="RadGridArrangement_ItemCommand"

>

.....

<ClientSettings enablePostBackOnRowClick="True">

<Selecting AllowRowSelect="True" />

</ClientSettings>

.........

<Triggers>

<asp:AsyncPostBackTrigger ControlID="RadGridArrangement" EventName="OnItemCommand" />

</Triggers>

</asp:UpdatePanel>

Thank you

ObjectDataSource Not Updating Grid

Hello everyone

I have a Telerik RadGrid on a page that uses an asp ObjectDataSource. This is a search page, and the user selects some options from drop down lists etc and then clicks a Search button. The ObjectDataSource uses a SelectMethod to retrieve the data from the database based on the parameters. I have set a breakpoint here and the ObjectDataSource returns the correct dataset. However the grid does not update. I have set AllowPaging = true, and if I change the page size, the grid updates with the correct data.

Many thanks for your help

RadCompression TroubleShoot

Hi,

I have radscriptmanager + radcompression combining and zipping up resources tremendously well on my dev environment.

Yet despite painstakingly checking web.config / code, only the combine (not compression) works on my test server.

Obviously something is amiss, but do you have any ideas (IIS 7 settings?) what could be stopping this as sure code is synced and struggling to see where to look.

Thanks
Matt
