Question

I tried this code but is not working ..

protected void btnAbc_Click(object sender, EventArgs e)
{
    string script = "<script language='javascript'>alert('abc');</script>";"
    ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script,true);
}

Pls advice.

Answer 1

You have double script tags. Add the script tags yourself:

protected void btnAbct_Click(object sender, EventArgs e) {
   string script = "<script type=\"text/javascript\">alert('abc');</script>";
   ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script);
}

Or let the method add it:

protected void btnAbct_Click(object sender, EventArgs e) {
   string script = "alert('abc');";
   ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script, true);
}

Not both.

Also consider if the RegisterStartupScript method is a better fit for what you want to do.
