Hi,

i m giving the Telerik Spreadsheet a try, because i used the WPF and Silverlight one. But as far as i can see, there s still some features missing.

I see that the only way to "customize" and "interact" with the spreadsheet is via provider. So, if i want to get data from DB i overwrite the GetSheets() method, and if i want to Save i override the SaveToWorkbook method.

1) But, what if i want to interact with the spreadsheet without postback?

2) Is there any way from listening to the Cell OnChange event ? (even on the client side would be fine)

3) In the CellContextMenu there is a OnClientItemClicked event. Are there any more events runnable from the client side?

Thanks for your support

RadControls Not Working on Ascx User Controls

I've been having a long and frustrating weekend of trying to get my RadControls to work on User Controls (ascx) files. For instance, the RadAsyncUpload control works just fine Client Side on a regular aspx page, but I'm having issues making it work on ascx files. I have yet to make a Server Side event work on the AsyncUpload events and thinking of just scrapping it for the regular Asp.net Upload control. Any way I can get some help within the next 24 hours on this? I'm already behind struggling with these controls? What is it that I'm missing to get them to work?

How can I get the mouse event object if I attach the client event inline?

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton" />
<script type="text/javascript">
function onclicktestbutton(sender, args) {
// I don't use window.event (it is non-standard)
}
</script>

Where can I set the event object??
I wanted to do it like this:

<telerik:RadButton runat="server" ID="testButton" OnClientClick="onclicktestbutton(event)" />

but we all know you can't insert paragraph on a telerik client event attribute because it automatically includes in the function the parameters (sender, args).

I don't want to export Hierarchical Grid Rows that have no child records.

Hi,

I am using version 2015.1.401.40 of the ASP.NET controls for AJAX.

I would think my question would be very common and easy to do.

I have a RadGrid with a MasterTableView and 1 DetailTable (GridTableView). I am using NeedDataSource for binding and it is all working fine.

Not all records in the master, have child records. For the rows that do not, I have hidden the expand/collapse button in the DetailTableDataBind event.

When I export to Excel, I want to expand all rows that contain a child record, so that those rows get exported. I was doing that in DetailTableDataBind by setting every GridDataItem .Expanded = True.

ISSUE:

The problem with this is that it expands and exports the child rows that say "No Child Records".

Question: How can I NOT have it export the gridtableview, if there are no child records?

In the DetailTableDataBind, if there are no child records I set the DetailTableView.Visible = False, but my export still contains a blank row (which is better than the "No Child Records", but not perfect).

Thanks,
Brent

Open custom dialog from RadWindow

Hi all,

I have an editable grid. When row is edited new RadWindow is opened. User can make some changes and after pressing save some serve-side code is executed. When specific conditions are met I want user response to continue correctly. I am using RadWindowManager and method RadConfirm for user response. It worked fine, but I need more possibilities now and I want to put 4 buttons instead of Ok/Cancel.

So I created new window DialogDeleteConfirm on my page



<telerik:RadWindowManager ID="radWindowManager1" runat="server" ViewStateMode="Disabled" >
  <Windows>
    <telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" DestroyOnClose="false" ViewStateMode="Disabled" KeepInScreenBounds="true"
      VisibleStatusbar="false"  Modal="True"  >
    </telerik:RadWindow>
    <telerik:RadWindow ID="DialogDeleteConfirm" runat="server" Width="450px" Height="120px" Modal="true">
        <ContentTemplate>
          <div style="padding: 10px; text-align: center;">
            <p style="text-align: center;">Do you want to delete items automatically?</p>
            <asp:Button ID="btnOk" runat="server" OnClientClick="returnArg('O'); return false;" />
            <asp:Button ID="btnSelection" runat="server" OnClientClick="returnArg('S'); return false;" />
            <asp:Button ID="btnKeepAll" runat="server" OnClientClick="returnArg('K'); return false;" />
            <asp:Button ID="btnCancel" runat="server" OnClientClick="returnArg('C'); return false;" />
          </div>
        </ContentTemplate>
    </telerik:RadWindow>
  </Windows>
</telerik:RadWindowManager>

According another discussion I simply replace my existing code

radWindowManager1.RadConfirm(messageToUser, "autoDeleteCallback", 450, 120, null, "");

by

DialogDeleteConfirm.VisibleOnPageLoad = true;

But it doesn't work and no window is displayed. Unfortunately there is no method in RadWindowManager to open window.

Can you help me how to open new window immediately?

Thanks a lot,
Petr
