GridDateTimeColumncolumn cannot able to displays dates before 1980/1/1.

[vinod]

Hello All,


basically GridDateTimeColumncolumn cannot able to displays dates before 1980/1/1. So i not able to use this for Date Of Birth for people who Born before 1980.
How to solve this issue without using template column. i am created RadGrid runtime & add GridDateTimeColumn dynamically.using following code.

  GridDateTimeColumn boundColumn = new GridDateTimeColumn();
                  boundColumn.HeaderText = strColumnName;
                  boundColumn.DataField = Item.Value;
                  boundColumn.UniqueName = strColumnName;
                  boundColumn.DataFormatString = "{0:d}";
                  boundColumn.PickerType = GridDateTimeColumnPickerType.DatePicker;                  RadGridRow.MasterTableView.Columns.Add(boundColumn);

Thanks In Advance....

Hello vinod,

You can set this in ItemCreated event. Here is an example:

if(e.Item is GridDataItem)
{
    ((e.Item as GridDataItem)["YourColumnUniqueName"].Controls[0] as RadDatePicker).MinDate = ...
}

Hello All I found solution for this problem ..

 RadGridRow.CreateColumnEditor += new GridCreateColumnEditorEventHandler(RadGridRow_CreateColumnEditor);

        {
            e.ColumnEditor = new RadDatePickerEditorClass.RadDatePickerEditor();
        }


Follwing Class used for datetime Picker Creation......


using System;
using Telerik.WebControls;


    public class RadDatePickerEditor: GridTextColumnEditor
    {
        private RadDatePicker picker;

        protected override void LoadControlsFromContainer()
        {
            this.picker = this.ContainerControl.Controls[0] as RadDatePicker;
        }

        public override bool IsInitialized
        {
            get
            {
                return this.picker != null;
