如何在onBlur事件上进行ASP.Net GridView回发？

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

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 2

您可以通过onBlur事件为Form对象调用Submit方法。

myForm.submit();

Answer 3

您可以在文本框上设置AutoPostback =“ True”，然后在Codebehind中将新值保存在事件处理程序中。
