Update Grid on EditCommandColumn

[Abdul]

Dear All, 

I am using Needdatasource for binding data to Radgrid and with DataTable.
 
I need to restrict the access to edit only one column of a row instead of all columns of that row.
I need to know a simple way to get the updated values of selected row.
I need to update other columns of the grid on the base of updated column on EditCommandEvent occured. 

Please Help.

Hello Abdul,

If you want to access certain columns when grid is in edit mode, you can set other columns/controls as ReadOnly. Sample code is given below.
C#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
   {
       if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
       {
           GridEditFormItem item = (GridEditFormItem)e.Item;
           TextBox txt = (TextBox)item["ColumnName"].Controls[0];
           txt.ReadOnly = true;
        }
   }

And for your second and third requirement, please go throuhg the following documentation.
Updating values in-place and with edit forms
Retrieving original values for edited item
Insert/Update/Delete at database level with queries

Actually not working I want the only one column to be displayed in edit form when I click on edit button. It makes the text field read only but they are still shown.

However this has worked for me.... 

protected void grd_report_NeedDataSource(object sender, Telerik.Web.UI.GridNeedDataSourceEventArgs e)
{
    if (obj_dt.Rows.Count!=0)
    {
        grd_report.DataSource = obj_dt;
        grd_report.MasterTableView.GetColumn("Column Name").EditFormHeaderTextFormat = "";
    }
}

protected void ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridEditFormItem && e.Item.IsInEditMode)
    {
        GridEditFormItem item = (GridEditFormItem)e.Item;
        item["Column Name"].Visible = false;
    }
}
