What is the best way to retrieve a hidden field value during the initial page load using asp.net?

<script type="text/javascript>"     
    var browserCompatibility = document.documentMode;
    document.getElementById("<%=hddnBrowserComp.ClientID %>").value = browserCompatibility;
    alert(browserCompatibility);
</script>

I am facing an issue where the hidden field value (hddnBrowserComp) is not displaying on page load. How can I ensure that it is populated correctly?

C#
if(!IsPostBack)
{
string x ="";
x = hddnBrowserComp.Value.ToString();
}

Answer №1

The sequence of execution is crucial - server side code takes precedence over client side code, making it imperative to follow this order for optimal functionality.

Answer №2

Eliminate the use of !IsPostBack

The issue arises due to the presence of !IsPostBack in your code. Remove it first and then test again.

string browserValue = "";
browserValue = hiddenBrowserComponent.Value.ToString();

Answer №3

Only compatible with Internet Explorer, the documentMode property reflects different modes based on IE versions.

5

Represents Internet Explorer 5 mode, also known as "quirks mode."

7

Reflects Internet Explorer 7 Standards mode.

8

Corresponds to Internet Explorer 8 Standards mode.

9

Refers to Internet Explorer 9 Standards mode.

10

Indicates Internet Explorer 10 Standards mode.

Answer №4

if(IsPostBack == false)
{        
    string data ="";
    data = hiddenBrowser.Value.ToString();

    ScriptManager.RegisterClientScriptBlock(this, GetType(), "Success", "alert('" + data +"');", true);

}

Give this a shot, it should do the trick
