I am using Telerik version 2011. 
I have created RadGrid header by using the below code. Under Each header there are sub headers. Each Sub Header is a Rad Grid Column. Each column having Filter Column. Whenever I click on filter button throwing a error in Visual Studio with popup message "Microsoft JScript runtime error: '_data' is null or not an object"

 GridHeaderItem newSubHeaderItem = new GridHeaderItem(FuelSummaryGrid.MasterTableView, 0, 0);
        newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = " ", BackColor = System.Drawing.Color.FromName("#61AAE6") });
        newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = " ", BackColor = System.Drawing.Color.FromName("#61AAE6") });
       newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Driving, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
        newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Shift, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
        newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Day, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
        newSubHeaderItem.Cells.Add(new GridTableHeaderCell() { Text = Week, ColumnSpan = 3, HorizontalAlign = HorizontalAlign.Center });
head.Controls.AddAt(0, newSubHeaderItem);

For the reference please find the images. 

Please help me how to resolve this issue.

Hi,

We have an issue in IE 7 and onwards in all Telerik releases after 2013.1.417.40.

Two of our pages use a grid with manually calculated footers which are then added in the Footer Event. I have rolled back through various versions of the telerik toolkit and found that the footer works as expected in 2013.1.417.40, but when I run it using all later releases the footer is offset with the manually built values appearing to the right of the grid.

Are there any known issues with this feature in subsequent releases?

It only appears to manifest itself when run through IE - all versions 7 to 11 - but is OK in Firefox and Chrome.

For the moment I have had to roll back to the 2013.1 release to avoid customer complaints.

Hi,

I want to show Sum and Avg at the same time while clicking  custom aggregates in the header Context.

I am able to show the Total Sum and Avg . But how do i calculate the sum and Avg for groupby columns and show in the group Footer item.

Any example or thought on this?

Best regards,
Satz

I want a binding ICommand to the Click event of a button in ControlPanelitem. But it does not work. And I Binding SelectedValue of RadDatePicker control in ControlPanelItem and it also does not work.

After upgrading to the latest release, there is a border around all my image buttons inside of Radgrid columns.
Prior to the latest update, I had the following css which worked fine for everything

When I tried using RadSearchBox, I found that the results drop down doesn't appear although the response is received successfully.
After some debugging, I found that the code appends the drop down element to the first FORM element it finds!
Here's the code:


ASP.Net restricts the existence of more than one FORM with runat=server, but I may have as many FORM elements as I want for other client side uses. Why supposing that there's only one FORM, while BODY should have been used for this, because there can't be more than one BODY.

I'm using context menu in RadGrid control in an iframe. But some items seem to be out of the screen, so I can't click them. Codes for js and RadGrid:

After upgrading to 2013 Q3 to 2013 Q3 SP1 , something is off with RadTextBox & MultiLine. Code that was working to split the multi lines into an array no longer works and I have to use a standard ASP TextBox. See code as follows.

I have a grid that has a GridButtonColumn in it.  I have a command name set and call the command name on the grid_itemCommand.  I have a hidden field called PKEY that I need to get the value of when the button on that row it clicked.  How can I get the value of that hidden field?  Right now all I get is  , but if I set the visibility to True I get the value.
