How can Check Page Load event the textbox value empty or not empty then textbox value can empty then insert the value other wise redirect the next page

Hi Krishna,

I think you want to validate the textbox,
at page load event you want to check whether text box has value or not,
Here is sample code you can make use of

protected void Page_Load(object sender, EventArgs e)
{
if (String.IsNullOrEmpty(txtbox.Text)) //your textbox name comes here
            {
                txtbox.Text = "Your string goes here";
            }
            else
            {
                Response.Redirect("About.aspx");
            }
}

Hope this helps you a bit.
