How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.

I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.

The following code works well as long as I pass a querystring value to the datalist.
Private Sub BindGrid() Dim id As Integer = Integer.Parse(Context.Request.QueryString("id")) Dim strConnString As String = ConfigurationManager.ConnectionStrings("Conn").ConnectionString Using con As New SqlConnection(strConnString) Using cmd As New SqlCommand() cmd.CommandText = "select Id, Name from tblFiles where Id=@Id"

However, the page errors with the message "Value cannot be null." if I don't pass a value. I know that DataList does not have an EmptyItem Property like a Gridview control. I do not want the page to error if I don't pass a value. Need info to deal with empty values in a datalist.
Most websites have pointed me to this code to use:
The 'list' throws an error. The error is "Too few type arguments to 'System.COllections.Generic.List". I am not sure if the code is written in C# and that is what is causing the error. It seems that it should work but I can not figure out the 'list' error.
