Question

How can I clear my textboxes after I click on cancel button in confirm message box. My message box script is,(In web application). If we cannot perform with this script message, Refer me another one.

 ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "confirm('Do you want to delete it ..!!');", true);

Answer 1

confirm('Do you want to delete it ..!!')

it returns true or false on the basis of what button you have clicked..

better to write a separate function and include it in your JavaScript file and call like the above way you are doing..

else you have to write the whole code inline, but looks messy..

ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "" +
    "document.body.onload = function(){"+
      "if(confirm('Do you want to delete it ..!!')==false)" +
        "{" +
           "document.getElementById('myTextBox').value='';" +
        "}"+
      "}", true);

Answer 2

   ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "confirm", "confirm('Do you want to delete it ..!!');", true) ? txtDate.text = string.Empty : txtdate1.text = string.Empty;
