Hey there,

I am not sure why do you need CommandName and CommandArgument for TextBox, as these are not properties of TextBox control, so CommandName and CommandArgument will be added as Attributes of the TextBox.
Here is an example showing how you can get them in the event:

C#

protected void TextBox_TextChanged(object sender, EventArgs e)
        {
            TextBox txt = (TextBox) sender;
            string commandArg = txt.Attributes["CommandArgument"].ToString();
            String commandName = txt.Attributes["CommandName"].ToString();
        }

Let me know if it helps.

Azee...

i want to find which text box get fair and then assign focus to next text box. These are used in gridview. So, how to find which text box changed please help me

You can use CommandArgument or CommandName's value to identify which TextBox was changed. I have shown you how to get those values. What is the problem now?
and What is the parent control of these TextBoxes?
