Hello,

I create a gridboundcolumn from codebehind and try to group it.
It throws an exception:

Unhandled exception at line 885, column 13 in http://server1/ScriptResource.axd?d=1A_JfTzkVI_BPK0wyueglza3uf3p5EQOp4lCh3bkZFj2kwIlPrGfNBqAYyJG42yrzLhNfZTtBWoYuqokkf-vNOdy8LQfqHEEJse-2Zpg5nGn_znQ0ma5rdc2XuV8eHZvGcbaSsZ0Wu1n7TPfMrcwAYGxAJyYoPMx7lFZ_2kSkbfeRFZ1GXIexwskAgJ3NeM67J1V_H9-C5a9cYJV09SQKA2&t=6119e399

Hi,

I have RadGrid and Edit Mode is popup. In Edit Popup, I have a button. This button call the RadWindow dialog.

My problem is that my dialog is only showing under RadGrid Edit Popup eventhough I set the Modal = "true" in RadWindow.

Is there a way to set the z-order?

I know that 

EditMode

="EditForms" is working but I have 100 of pages are using EditMode="PopUp".

 

 

 

 

 

Thanks,
Alex

Hello,

I have a Grid that uses a template column with an AsyncUpload control in edit Item Template.  On update of row I need to get the original value of the cell (fileName) before update to delete file then complete update event.  What would be the best approach?

Thank you,
Bryan

how to determine the id parent of adding in TreeList?

how to campare datetime in radgrid itemdatabound ?

I have code that shows a Modified label when there have been changes to the editor and it works great, except when the editor is in full-screen mode and then the label cannot be seen.

I'd like to add the update panel (with the modified label) to the status bar - the area (div class="reModule" span) that contains the text "Words: 0   Characters: 0".

I've tried moving the update panel with the following code, but it doesn't work even though it finds the controls.  In IE, the update panel no longer is visible and in Chrome, it apparently has no effect.

var reModuleDivs = document.getElementsByClassName("reModule");
var reModuleDiv = reModuleDivs[0];
var notesEditorUpdatePanel = document.getElementById("<%= notesEditorUpdatePanel.ClientID %>");
reModuleDiv.appendChild(notesEditorUpdatePanel);

Is there any simpler method to go about adding an update panel / label to the bar that contains the status text?

I keep getting http://demos.telerik.com/ErrorPageResources/error.aspx?aspxerrorpath=/aspnet-ajax/default.aspx
whenever I click on any link within Telerik.com (or from anywhere) referring to ASP... live demos.

Am I missing something?

eg from http://www.telerik.com/support/demos/developer-tools-demos.aspx click on Launch ASP.NET AJAX Demos and I get error page.

            SqlDataAdapter da = new SqlDataAdapter(sql, conn);
            da.Fill(data);

            List<AutoCompleteBoxItemData> result = new List<AutoCompleteBoxItemData>();

            foreach (DataRow row in data.Rows)
            {
                AutoCompleteBoxItemData childNode = new AutoCompleteBoxItemData();
                childNode.Text = row["NAME"].ToString();

            }

            AutoCompleteBoxData res = new AutoCompleteBoxData();
            res.Items = result.ToArray();

            return res;
}


Some Error is occured when public static AutoCompleteBoxData GetCompanyNames(object context) replace to public AutoCompleteBoxData GetCompanyNames(object context) [remove static keywords]

THE SERVER METHOD  'GetCompanyNames
'  FAILED.

Hello -

I'm using the the RadAsyncUpload and i've wired up a client side handler to the OnClientFileSelected event. My goal is to alert the user that their file is not a valid extension and then  reset the control by removing the file that they attempted to upload. According to your documentation here I should be able to make use of the remove_fileSelected method to remove the file that the user attempted to upload and thus hopefully reset the control so the user can do a new upload.

The problem I have is I can't find any documentation on your site for what the signature is for remove_fileSelected or how it should be used - what parameter needs to be passed to it. Here is my handler code, please help, and if possible please expound your documentation so this is more clear.

Thanks.
