Hi world,
My Code is :
I call this page from another Page :

HTML

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>

    <script type="text/javascript">
       
        function setinformation() {

            var oMyObject = window.dialogArguments;
            document.getElementById('<%=GridviewTypeT.ClientID%>').value = oMyObject.GridViewType;
        }
       
        
    </script>

</head>
<body  onload="setinformation();">
    <form id="form1" runat="server" >
    <div>
        <asp:HiddenField ID="GridviewTypeT" runat="server"  />
    </div>
    </form>
</body>
</html>

My Question is that how can i call function setinformation() before Page_Load so in Page Load i can have value in GridviewTypeT Something Like this :

protected void Page_Load(object sender, EventArgs e)
        {
                        
            if (GridviewTypeT.Value == "Ghata")
            {

            }
            else if (GridviewTypeT.Value == "Khadamat")
            {

            }
        }

But now it doesnt have any value and after Page_Load finish then it execute the function setinformation() and will get Value.
So i want the value befor Page_Load.

Thanks in advanced!

You can't.

[explanation]

The javascript will not execute until the DOM is ready, in other words, all the HTML has to download to the browser, before the JavaScript will initialize.

I think you need to call the window.onload for javascript, like page load, and make it call your function. The post says that it will load a fucntion before the DOM is ready.

I may be wrong on this, I always wait for the DOM, and do stuff like that on the server side using page load.

Thanks but not used...
I have tested this before and didnt get any result :

HTML

<script language="javascript" type="text/javascript">
        
      window.onload=   function c() {
        document.getElementById('<%=TextBox1.ClientID%>').value = "Helo";
        }
       
    </script>

I don't know what your trying to do, but the link did offer several suggestions.

If you want to execute some javascript on page load, you use the body tag and enter a javascript function to run on your tag onLoad.

<script>
  function initialize() {

    // Map initialization

  }
</script>
<body onload="initialize()">
  <div id="map_canvas"></div>
</body>

Google Maps uses this, to initialize the map object, and request map data before the page is drawn in the browser. When the map canvas is available in the DOM, the map object then draws the map in the map canvas.

If you want to execute some javascript when the DOM intializes, usually 2 seconds after the page paints in the browser window,

window.onload = function() {
     init();
     doSomethingElse();
};

function init() {
     var tempValue = document.getElementById(txtHiddenDomain).value;
     alert(tempValue);
     
     document.getElementById(txtHiddenDomain).value = "test value"
}

function doSomethingElse() {


}

If you can't get the value, then double check your ID attribute for the control. If you use the controls ID, then perhaps the ID is changing to another value, so you have to hard code the ID using id="_txt_textbox"

you had your id wrapped in <% %>, so do a response.write(<% %>) and double check the value printed.

Thanks for the ans.
My aim is that when this page loaded it should show a gridview.
now the datasource of gridview depend on what i will send from other pages.(i mean that i just send the type of gridview and in the page_Load it will fill it depending on the type i sent).
So i should know the value of GridviewTypeT.Value in Page_Load for when the page load the gridview will also load automatically.

if (GridviewTypeT.Value == "Ghata")
           {

           }
           else if (GridviewTypeT.Value =="Khadamat")
           {

           }
