[Solved] readonly column dependent of another (hidden) field

Hi,

I want to make a column in a RadGrid readonly dependent of the value of a different field in the dataset. This field is not shown in the grid. How do I do this?

Check Box and Image in Unbound Grid

I have an application where I populate the RadGrid from a CSV file (ie using it in unbound mode). I define the columns as

Dim dt As New DataTable()

dt.Columns.Add("Date")
etc
and populate them using

Value = {Dte$, Item$, Type$, Recordid$}

dt.Rows.Add(Value)

All this works fine.

I now need to add a checkbox and image column. Can you direct me to a sample. I was not able to find any.

Thanks

Allen

RadDatePicker - Element 'DateInput' is missing required attribute 'runat'

Ok, in Visual Studio 2008, after simply dragging a RadDatePicker (Ajax) onto my form, I'm seeing the following warnings in the error list...

Validation (ASP.Net): Element 'DateInput' is missing required attribute 'runat'.

and

Validation (ASP.Net): Element 'Calendar' is missing required attribute 'runat'.

I imagine this is a bug with your control (probably in the [ToolboxData()] for the RadDatePicker class)

My question is: should I go ahead and manually add "runat='server'" for those tags in my declarative? Or is there some trick to make Visual Studio not display these warnings?

Thanks.

RadDatePicker filter not working correctly when changing DisplayDateFormat

Hi there,

I am using a RadDatePicker filter with the DisplayDateFormat="MM/dd/yyyy" and filter function=LessThanOrEqualTo. It seems the filter not returning the correct data, for example, if I set the RadDatePicker ="07/12/1996", the filter returning date prior to December 7th, 1996, while I am actually expecting date prior to July 12th, 1996.

Please see my following code (database is NorthWind), any help is greatly appreciated.
