hmm ok if u knw the answer,then just explain,otherwise dont insult,bcoz nobody did't gt knowledge from their own thinking...even u...sory to say tis bcoz i'm a begginner,don't discourage me.....

and also y we use render in above code

Callbacks are not supported on TemplateField because some controls cannot update properly in a callback. Turn callbacks off on 'GridView1'.

i got this error

DEFAULT.aspx.cs....
protected void Page_Load(object sender, EventArgs e)
{
Calendar1.Visible = false;
}
protected void Calendar1_SelectionChanged(object sender, EventArgs e)
{
TextBox1.Text = Calendar1.SelectedDate.ToString("MM/dd/yy");
Calendar1.Visible = false;


}

protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
if (Calendar1.Visible = false)
{
Calendar1.Visible = true;

}
else
{
Calendar1.Visible = true;

}
}
}
