How do I make an ASP.Net GridView postback on an onBlur event?

Question

I have an ASP.Net GridView, with two columns ("ID" and "name"). The name column is editable via an <asp:TextBox>. What I want to do is have the grid trigger its update event when the user clicks away from an editable cell.

I know I can attach an onBlur event handler to the TextBox to retrieve the value when the user clicks away. However, I don't know how to trigger the GridView's update event programmatically through JavaScript. Any suggestions?

Answer 1

You could call the submit method for your Form object from the onBlur event.

myForm.submit();

Answer 2

On your TextBox set AutoPostBack="True". This will cause a postback when the client change event fires, which is probably what you want rather than blur. Attach a TextChanged handler to the textbox and you can call your grid update method from there.

you can get the row index for the textbox that triggered the event like this:

protected void TextBox2_TextChanged(object sender, EventArgs e)
{
    GridViewRow gridRow = ((GridViewRow)((TextBox)sender).NamingContainer);
    Console.WriteLine(gridRow.RowIndex);
}

Answer 3

You could set AutoPostback="True" on your Textbox and in the Codebehind save the new valuein the Event Handler.
