</html>

I am trying to set today date as default using this code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
 
public partial class members_Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        RadDatePicker1.SelectedDate = DateTime.Now.Date;   
   
    }
     
}
I get the error message "Unknown entity RadDatePicker1". So basically it is not reachable in code behind.
I saved, rebuild, rebooted, update, but the problem is still there. I can I solve this problem?

Hi Felice,

In order to access the RadDatePicker inside the EditForm of RadGrid, you need to write the code in the OnItemDataBound event of RadGrid as follows.

C#:
protected void RadGrid1_ItemDataBound(object sender, Telerik.Web.UI.GridItemEventArgs e)
{
    if (e.Item is GridEditableItem && e.Item.IsInEditMode)
    {
        GridEditableItem item = e.Item as GridEditableItem;
        RadDatePicker picker = item.FindControl("RadDatePicker1") as RadDatePicker;
        //your code
    }
}

Thanks,
Shinu.
