Hello Janaki,

You can add a DatePicker dynamically using the following code.
C#:
protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e)
{
 if (e.Item is GridEditFormInsertItem )
 {
    GridEditFormInsertItem item = (GridEditFormInsertItem)e.Item;
    RadDatePicker pkr = new RadDatePicker();
    pkr.ID = "RadDatePicker1";
    item["UniqueName"].Controls.Add(pkr);
  }
}

Thanks,
Princy.

Hi Princy!
I´ve got a treelist with two datepickers added dynamically when I am going to insert a new row

How can I validate when press the save button inside the treelist, the date selected in the first fileld is minor than the second one?
and show the appropriate error message?

Thanks,
Franklin.

Hello Franklin,

You can use CompareValidator for comparing the dates. Here is the sample code.
C#:
protected void RadTreeList1_ItemCreated(object sender, Telerik.Web.UI.TreeListItemCreatedEventArgs e)
{
 if (e.Item is TreeListDataInsertItem)
 {
   TreeListDataInsertItem item = (TreeListDataInsertItem)e.Item;
   CompareValidator com = new CompareValidator();
   com.ID = "CompareValidator1";
   item["ColumnUniqueName"].Controls.Add(com);
   RadDatePicker pkr1 = new RadDatePicker();
   pkr1.ID = "RadDatePicker1";
   item["ColumnUniqueName"].Controls.Add(pkr1);
   RadDatePicker pkr2 = new RadDatePicker();
   pkr2.ID = "RadDatePicker2";
   item["ColumnUniqueName1"].Controls.Add(pkr2);
   RadDatePicker picker1 = (RadDatePicker)item.FindControl("RadDatePicker1");
   RadDatePicker picker2 = (RadDatePicker)item.FindControl("RadDatePicker2");
   DateTime startDate = Convert.ToDateTime(pkr1.SelectedDate);
   CompareValidator compValidate = (CompareValidator)item.FindControl("CompareValidator1");
   compValidate.ControlToValidate =picker1.ID;
   compValidate.ControlToCompare = picker2.ID;
   compValidate.ValueToCompare = DateTime.Now.ToShortDateString();
   compValidate.Type = ValidationDataType.Date;
   compValidate.Operator = ValidationCompareOperator.LessThanEqual;
   compValidate.ErrorMessage = "EndDate should not be less than StartDate"
 }
}

Thanks,
Princy.
