Hello, I have a couple of issues with the grid control and column sizing. Here is my scenerio; I have grid inside a div that is set for 100% width. I did look at http://demos.telerik.com/aspnet-ajax/grid/examples/client/scrolling/defaultcs.aspx and near as I can tell I did it all correctly.
Issue 1:
I have two columns that are given a header style width of 100px. When I open the form the two columns are split equally to the width of the window. My expectation is that they are two columns at 100px each with a filler block taking up the rest of the space. I open the form and then manully resize the columns back to 100px this is indeed what I get.
Issue 2:
I have 6 columns at 150px each. Sometimes (not consistently) the grid wil shrink the columns rather than display a horizontal scroll bar. So I end up with 6 columns at 75px each rather than getting a scroll bar.
Issue 3:
Why is it that when I fix the column headers (UseStaticHeaders) There is a white box at the top of the scroll bar rather than a column header. It looks correct if I have UseStaticHeaders turned off.
Here is the page
And the code behind

Hi,
I have a few questions:
Environment: RadControls for ASP.net 2009 Q2.
1. On the commanditems strip, I would like to show some custom commands, like an edit button when clicked, would put certain cells in certain rows in edit mode based on some business rules. I would also like to put an "Update" button on this strip which will fire a custom method on the server to update the edited rows in the grid. These buttons will also be hidden under certain conditions. How would I do that?
2. I don't see any property either at desgin time or in code to add the button "Export to Excel" to this commanditem strip. The online examples on your site have some "ShowExportToExcelButton" property set. But I don't see it at either design time or at runtime. How do I do this?
3. I would also like to set some of the cells in certain rows, only in certain columns, non-editable and some others editable (when Edit button clicked). What is the appropriate event handler to put this code in?
Thanks
Babu.

Hello,
I tried to adopt what was done in your MVC forum sample project for the RadPanelBar. What I want to do is add a series of RadPanelItem's that contain a RadListBox control as its interface. The RadListBox will be data bound. But I'm getting an error about adding controls after prerender. Is there something I can do to remedy that, or do the RadPanelItem/RadListBox have to be hard coded in?
My approach was:
<%
if (Model.Groups != null)
{
foreach (var group in Model.Groups)
{
RadListBox box = new RadListBox();
box.DataSource = group.Items;
box.DataTextField = "Name";
box.DataValueField = "Key";
box.DataBind();
RadPanelItem item = new RadPanelItem(group.Name);
item.Controls.Add(box);
rpbContacts.Items.Add(item);
}
}
%>
<tel:RadPanelBar ID="rpbContacts" runat="server" />
Thanks.

Hi,
Couple of issues with 3.5 dll :
1. If we use the Telerik.Web.Ui.dll for framework 2.0 i.e. Bin/Telerik.Web.UI.dll, we are able to cast the e.Item.DataItem as DataRowView
(in ItemDataBound event handler) and access the values from the corresponding row in the datasource. But when we use the dll for 3.5 framework i.e. bin35/Telerik.Web.UI.dll , it doesn't allow the GridDataItem's DataItem property to be cast as DataRowView. It shows it as a Dynamic Class. The interesting thing is it allows the GroupHeaderItems to be cast as DataRowView.
Can you please let me know , how to access the corresponding row Data values from the DataSource using dll for 3.5 framework.
2. Also, I have a GridCalculatedColumn which has a 'ISNULL' function in its expression and works fine with 2.0 dll. This same code gives error when it references the 3.5 dll.
e.g.
Thanks,

Hi,
Please could you tell me what RadGrids are inherited from (i.e. are they inherited from the .net gridview control) or something else. The reason for the question is because we want to be able to extend the grid to allow multi-row (spreadsheet-like) editing. Is this type of editing already available and I just haven't seen it yet?
Regards
Robert
