I'm having trouble trying to set a value to this property. When the calendar control is displayed alone on a webform (NOT inside a datagrid), the property is READ and WRITE. I am able to set a value to it.
When the control is placed inside a datagrid column, I can't set the value of the SelectedDate property. It informs me that it's READONLY.
Below, is the HTML on the ASPX page of what is happening:

Here is the code-behind:
<code>
Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Calendar2.SelectedDate = "01/01/04"
End Sub
Private Sub DataGrid1_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.DataGridCommandEventArgs) Handles DataGrid1.ItemCommand
Dim myDatagridItem As DataGridItem
Dim c As Calendar
For Each myDatagridItem In DataGrid1.Items
c = myDatagridItem.FindControl("Calendar1")
'c = DirectCast(myDatagridItem.FindControl("Calendar1"), Calendar)
c.SelectedDate = "01/01/04"
Next
'and i also tried this:
c = DirectCast(e.Item.FindControl("Calendar1"), Calendar)
c.SelectedDate = "01/01/04"
End Sub
</code>
In the page load event, the date gets set fine, but not in the above event. I even tried placing the above code inside the page load event as well (just setting calendar1.selecteddate to a date, but still didn't work).
Can someone please inform me how I can set the SELECTEDDATE property. The reason being, is that once the data is loaded into a dataset, I want to set the value of the date on the calendar control to the SelectedDate.
When the control is placed inside a datagrid column, I can't set the value of the SelectedDate property. It informs me that it's READONLY.
