I need to copy data from a  RadDatePicker  Control which is  inside a RadGrid using GridTemplateColumn to a Label Control also in the same RadGrid also using GridTemplateColumn   when a Session Variable is True. My Situation is if Session Variable is true, Copy data form :
When Session Variable is True, Copy data from this control below
<
telerik:GridTemplateColumn HeaderText="Start Date" UniqueName="StartDate"
 Visible="false">
        <ItemTemplate>
         <asp:Label runat="server" ID="startdate" Text='<%# String.Format("{0:d}" , Eval("StartDate")) %>'>
          </asp:Label
         </ItemTemplate>
        <EditItemTemplate>
       <br />
  <telerik:RadDatePicker ID="picker3" runat="server" DbSelectedDate='<%# Bind("StartDate") %>'>
</telerik:RadDatePicker>            
<
asp:CustomValidator ID="CustomValidator3" ControlToValidate="picker3" ErrorMessage="This field was incorrect"
           runat="server" OnServerValidate="CustomValidator1_ServerValidate">
     </asp:CustomValidator>
     </EditItemTemplate>
            </telerik:GridTemplateColumn>


To Destination Control
<telerik:GridTemplateColumn HeaderText="Finish Date" UniqueName="FinishDate">
                    <ItemTemplate>
            <asp:Label runat="server" ID="FinishDate" Text=" ">
                  </asp:Label
            </ItemTemplate>
    </telerik:GridTemplateColumn>
An idea is welcome please

Hi Ebenezer,

I guess you want to show the selected date value in the label, when the Grid is in EditMode. Please try the following code snippet.

ASPX:
<EditItemTemplate>
    <telerik:RadDatePicker ID="picker3" runat="server" AutoPostBack="true" DbSelectedDate='<%# Bind("Startdate") %>' OnSelectedDateChanged="picker3_SelectedDateChanged">
    </telerik:RadDatePicker>
</EditItemTemplate>

C#:
protected void picker3_SelectedDateChanged(object sender, Telerik.Web.UI.Calendar.SelectedDateChangedEventArgs e)
{
    RadDatePicker datepicker = (RadDatePicker)sender;
    GridEditFormItem eitem = (GridEditFormItem)datepicker.NamingContainer;
 
    if//(Your condition to check Session Variable is true)
   {
    GridDataItem ditem = (GridDataItem)eitem.ParentItem;    
    Label lbl= ditem.FindControl("FinishDate")as Label;      
    lbl.Text = datepicker.SelectedDate.ToString();
   }       
}

Thanks,
Princy

Hi Princy,
Thanks for your response. I need to show the selected date value in the label, when the Grid is in Normal Mode since users are not allowed to edit the label. That is my issue.

Hi Ebenezer,

Please try the following code snippet to bind the values to a Label in GridTemplateColumn. If this doesn't help, please elaborate on your required scenario.

C#:
protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
 {
    if (e.Item is GridDataItem) // Check here for session condition as well
     {
         GridDataItem item = (GridDataItem)e.Item;
         Label lbl = (Label)item.FindControl("FinishDate");
         lbl.Text = DataBinder.Eval(item.DataItem, "StartDate").ToString();
     }
 }

Thanks,
Princy
