In a previous forum thread ( http://www.telerik.com/community/forums/aspnet-ajax/grid/is-this-conventional-practice-with-a-radgrid.aspx ) 'Marin' suggested that I could move the RadComboBoxes to the ItemDataBound event.
First of all, keep in mind that the RadComboBoxes have conventional Bind statements on their SelectedValue property and that they are in a RadGrid FormTemplate.
When I tried to move their population calls to ItemDataBound (within a 'if (e.Item is GridEditFormItem && e.Item.IsInEditMode)' block) it crashed.
So I suppose my question has two parts.
First: Is there a demo that does this?
Second: How do I prevent a RadComboBox from crashing on a bad incoming value, i.e. one that isn't in it's list?
(This is more of a deja vu thing. I'll swear I've done this before but I can't find the code...)

I need to display grid with pending changes to a set of records. The way I envisioned it, each master row would be a record itself. When you expand the row, the pending changes would be presented in a detail row. However, since each row will have different pending changes, the layout of this detail row would be different. I wanted to hide/display columns of each individual detail grid depending on pending changes to their master row record. So, if there's no pending change to a property, the corresponding column on this row will be hidden. I've attached the picture illustrating my attempt.
I can't find a way to hide columns of the detail view for an individual row and I don't know if it's even possible. Does layout for each detail view have to be the same? Is detail view even a right way to accomplish this? Should I use nested view instead?
I'd appreciate help pointing me to the right approach with some tips on what event handlers I should use to accomplish this.
Thanks,
Alex

I am using a RequiredFieldValidator and a ValidationSummary within a usercontrol within RadGrid EditForm.
The validation works fine, but I have set the RequiredFieldValidator to show an * beside the control being validated (Text="*") and the ErrorMessage to something more discriptive: ErrorMessage="Name is required."
The problem however is that when the cotrol errors out, ErrorMessage shows in both the ValidationSummary and next to the erroring control where the * is expected per the property (Text="*"). I need the * to show because it is better for my layout and consistent with validation outside the radgrid elsewhere on the page. The longer more verbose Message="Name is required."
messes up the layout.
Has anyone had this problem before. I have never seen the RequiredFieldOperator behave like this before so I can only see the RadGrid as being the problem.
Someone please help.

For a bar chart, as the rotation angle for the x axis item label increases, the label continues to be centered on the series item. When the x axis becomes crowded, it is impossible to determine what label is associated with a series item. Other vendors products have the ability to align the upper end of the x axis item label with the series item that it is associated with. Is there a way to accomplish this either the RadChart or RadHtmlChart?

I have followed the example on the site for implementing the RadFilter with a grid. The control displays, but I get the following error:
Line: 6
Error: Sys.WebForms.PageRequestManagerServerErrorException: Parameter cannot be null or empty.
Parameter name: fieldName
This occurs whenever I click the add expression button.
Any help would be appreciated.
Thanks...Brian

Just had something odd happen.
I have a fairly conventional RadGrid with a FormTemplate popup editor. This has been working normally.
On the FormTemplate is a RadComboBox and I've been trying to attach a function call to the OnClientLoad event with the eventual intent of doing some intialization to the popup.
This function is defined as follows:
It appears that the $find call is what's disabling the popup. If I comment that out, the popup displays normally.

}
}
