Hello, I have a textbox and a gridview.

Initially the gridview was hidden, I used modal popup extender to display gridview on textbox click.

On textbox mouse click, I will get the gridview displayed.

Now, what I need is to display the gridview on ENTER Click (i.e., from keyboard) in the textbox and not with any other. Can anyone help?

Thanks.

C#

private void TextBox_KeyDown(object sender, KeyEventArgs e)
       {
           if (e.KeyCode == Keys.Enter)
           {
               DataGridView1.Visible = true;
           }

Thanks, but I am not getting output. I have written like this.

design:
<asp:TextBox ID="TextBox1" runat="server" OnKeyDown="TextBox1_KeyDown()"
AutoPostBack="True">
in cs:

private void TextBox1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Enter)
{
GridView1.Visible = true;
}
}

is it correct?

write this code on TextChanged Event of TextBox

Sorry,

I am getting this error after writing code in textbox changed event.

CS1061: 'System.EventArgs' does not contain a definition for 'KeyCode' and no extension method 'KeyCode' accepting a first argument of type 'System.EventArgs' could be found (are you missing a using directive or an assembly reference?)
