var textBox = radSellerDataForm.ChildrenOfType<TextBox>()
     .Where(c=>c.Name == "txtSellerIdentifier").SingleOrDefault();
if(textBox != null)
{
     string value = textBox.Text;
}

Good am Amitkumar,

What do you want to do with the cancel button programmatically?

The cancel button event can actually be captured at the EditEnding event of the RadDataForm please see code below:

private void myRadDataForm_EditEnding(object sender, Telerik.Windows.Controls.Data.DataForm.EditEndingEventArgs e)
        {
            if (e.EditAction == Telerik.Windows.Controls.Data.DataForm.EditAction.Commit)  //for the OK Button
            {
             .....           
            }
            else if (e.EditAction == Telerik.Windows.Controls.Data.DataForm.EditAction.Cancel) //for the Cancel Button
            {
             .....
            }
       }

Then do the commit changes in the EditEnding event of the RadDataForm like the code below:
private void myRadDataForm__EditEnded(object sender, Telerik.Windows.Controls.Data.DataForm.EditEndingEventArgs e)
        {
            if (e.EditAction == Telerik.Windows.Controls.Data.DataForm.EditAction.Commit)  //for the OK Button
            {
             .....           
             myDomainContext _DomainContext = (myDomainContext)(myDS.DomainContext);
             this.myDS.SubmitChanges();            
            }
            else if (e.EditAction == Telerik.Windows.Controls.Data.DataForm.EditAction.Cancel) //for the Cancel Button
            {
             .....
            myRadDataForm.CancelEdit();
            }
       }

hope the above code gave you some idea with your inquiry.

Thanks :)
