After the upgrade yesterday, when an event is fired using AjaxPanel or AjaxManager, the first column of the grid is showed reduced (I'm using a button to change the page view on a multipage, but the grid is on second page) then if I apply sorting on a column the grid show well, next change the page and wend return to the page of the grid this is showed bad.
The same error is doing when I have a grid and RadWindow is showed over a grid (in modal mode).

Hi,

 In our project we are using the telerik grid on Invoice screen to display item list. 
 We are adding item from text box and adds it to grid dynamically using UpdateGrid javascript function. 
 
 Issue:
  When we add the new item to grid. It adds to grid as last row. But grid is not scrolling to last row.
  We want to scroll grid to last row every time we add new item.
  
  Below are the settings used in grid which did not work out:
<ClientEvents OnRowSelected="rowSelected" OnRowCreated="OnRowCreated" OnRowCreating="OnRowCreating" />
<Scrolling AllowScroll="True" EnableVirtualScrollPaging="True" UseStaticHeaders="false" SaveScrollPosition="true" />
  
Please help.

It is a bit disappointing that Enum filtering is not supported. I would recommend you re-evaluate the need for this type of support given the fact that the Entity Framework now supports Enums (I think as of 4.1?) AND since the RadGrid supports binding against the Entity Data Source.

I think you'll find that Enums are very popular when using the Entity Framework Code First approach. It would be SUPER useful if your development team could find a way to support this. It would make an already great control even greater!

I have created a dynamic hierarchical grid bind with dataset.
I would like to have provision for Add/Update/Delete. I could not do that. even i don't see any demos for the same to my knowledge that is not doable. Is there a way to do that please redirect me?

The following steps create this issue:
1. Use html 4
2. Use telerik AJAX (For consistency)
3. Set a radgrid with some columns that reach beyond the extent of its element (such that it requires horizontal scrolling). Use at least four columns. One being the GridClientSelectColumn.
4. Have the following settings:
Control Settings: 
AllowPaging=true,AllowSorting=true,AllowFiltering=true,AllowFilteringByColumn=true,AllowMultiRowSelection=true

Control Events Used: NeedDataSource,OnItemDataBound
Client Settings:
EnablePostBackOnRowClick=false,Resizing AllowColumnResize=true, Selecting AllowRowSelect=true,UseClientSelectColumnOnly=false,Scrolling,AutoGenerateColumns=false,AllowScroll=true,UseStaticHeaders=true

Important note: Retain data on the server, rebind, and, on item databound, select the previously selected rows.

Set up a button to perform some action on the selected rows and have this action use AJAX such that this action depends on the currently selected rows in the RadGrid.

5. Scroll away from the selection checkboxes
6. Select some rows in your RadGrid
7. Perform your action with AJAX
If all was set up correctly, your grid should have been rebound with the previously selected rows re-selected. The RadGrid should still be scrolled to its previous position.
8. Perform your action with AJAX again. Here's the bug, the grid states that it has no selected items; however, the client shows that there are items selected in the UI.

This may be related to "RadGrid's last selected item index is not persisted correctly when two or more postbacks are triggered from external controls."

Hi,
I am adding items to radgrid using cleint side javascript using updateGrid function.
My grid structure is DIV -> Table -> Radgrid.

I am adding rows dynamically based on the values added from the external fields.
I want the grid scroll bar at the last row position.
I have already tried all settings suggested from telerik site but was no success.
Below are the settings added which did not worked out:
<ClientEvents OnRowSelected="rowSelected" OnRowCreated="OnRowCreated" OnRowCreating="OnRowCreating" />
<Scrolling AllowScroll="True" EnableVirtualScrollPaging="True" UseStaticHeaders="false" SaveScrollPosition="true" />

Please help.

Regards.

Design-time error when SelectMethod property added.

The RadGrid OnDataBindingFailed event does not fire when WCF/WebService returns an IIS 500 Errror page.

It DOES, however, fire when IIS returns a proper 500 error JSON response.

In my case, the former was happening because my ASP.NET WCF services were incorrectly configured and thus throwing a standard IIS 500 error page. RadGrid should recognize the IIS 500 page as failure and spawned a OnDataBindingFailed  event.

NOTE: For example, RadScheduler *does* correctly interpret the IIS 500 page as a failure (RE: OnClientRequestFailed).

Had a script to invoke filter button on enter key in the Filter header context menu of rad grid. This worked fine in Telerik DLL File version - 2010.2.929.35 but recently we upgraded to latest DLL which is File version - 2012.2.912.40 and it stopped working. Could you please help me in resolving this issue?

Code used in ASpx.cs was
 void HeaderContextMenu_ItemCreated(object sender, RadMenuEventArgs e)
        {
            if (e.Item.Value == "FilterMenuContainer")
                {
                    RadTextBox HCFMRTBFirstCond = e.Item.FindControl("HCFMRTBFirstCond") as RadTextBox;
                    HCFMRTBFirstCond.ClientEvents.OnKeyPress = "PressFilterButton";

                    RadTextBox HCFMRTBSecondCond = e.Item.FindControl("HCFMRTBSecondCond") as RadTextBox;
                    HCFMRTBSecondCond.ClientEvents.OnKeyPress = "PressFilterButton";

                }
            }

Javascript code is
function PressFilterButton(sender, args) {

    var c = args.get_keyCode();
    if (c == 13) {
        var btnFilter = null;
        var btnref = sender._clientID.substring(0, sender._clientID.indexOf("RTBFirstCond")) + 'FilterButton';

        btnFilter = document.getElementById(btnref);
        
        if (btnFilter != null) {
            btnFilter.click();
        }
    }
}

In HeaderContextMenu was made a typo in item value. TopGroupSeparator is typed as TopGroupSeperator. I've wasted 10 minutes to find out why JS code is not working.
