Can you add a bit more detail about what you are trying to actually achieve, as surely no-one is logged in to the server to recieve such a message

protected void btnConnect_Click(object sender, EventArgs e)
{
try
{

dbquery.getconnection(txtsname.Text, txtuname.Text, txtpwd.Text);
pnlDB.Visible = true;
pnlCN.Visible = true;
ddlDB();
}
catch (Exception ex)
{
lblex.Visible = true;
string p = ex.Message.ToString();
Response.Write("<script language='javascript'>alert(" + p + ")</script>");

lblex.Text = p;

pnlDB.Visible = false;
pnlCN.Visible = true;
}

}

:doh: I thought OP wants to see the error message on server itself, so I suggested logging.

Solution 2

I would suggest you to log the errors instead of showing message box at serverside.
Check the google[^] links to know more.

Solution 3

I think you forgot the single quotes around the message string in alert method,

Response.Write("<script language='javascript'>alert('" + p + "')</script>");

Solution 4

You just add the following code

ClientScript.RegisterStartupScript(GetType(), "alert", "alert('Your message');", true);

Please do not use Response.Write as it will mess up your css.
