RadButton Call Alert

[Luffy]

Hello, what i need for this radalert is when I clicked on the button. If the textbox is nothing, it will alert that textbox is empty and if there's something in the textbox , it will prompt that upload success.

How can i achieve that? 

Thanks

Hello Sherman,

You can show radalert and radprompt from server side as shown below.

C#:

protected void btnToggle1_Click(object sender, EventArgs e)
{
  if (txtbox.Text == "")
   {
     RadWindowManager1.RadAlert("TextBox is Empty", 330, 100, "Server RadAlert", "RadalertCallBackFn");
   }
   else
   {
     RadWindowManager1.RadPrompt("Server RadPrompt: Upload Success", "RadPromptCallBackFn", 230, 100, null, "Server RadPrompt", "12");
   }
}

Javascript:

function RadalertCallBackFn(arg)
{
   radalert("<strong>radalert</strong> returned the following result: <h3 style='color: #ff0000;'>" + arg + "</h3>", null, null, "Result");
}
function RadPromptCallBackFn(arg)
{
   radprompt("<strong>radprompt</strong> returned the following result: <h3 style='color: #ff0000;'>" + arg + "</h3>", null, null, "Result");
}

Thanks,
Princy.
