binding a constant value to a asp.net hiddenfield

Hello,
I have an aspx page (Test.aspx) and a class (Constants.cs).
The aspx page has a single Asp.net HiddenField.
The Constants.cs class has a list of some public constants defined.

I am not able to bind the value of the hiddenfield with a constant (defined in Constants.cs) during the design time. I need to explicitly call hiddenField.DataBind() method in my Page_Load() method at the run time.

The code that I am using to bind the "Value" property of the HiddenField is:

<asp:hiddenfield id="hdnPosition" runat="server" value="<%# Constant.Position%>">

The Value property of the hiddenField is set only when I call the hdnPosition.DataBind() method in my C# code.

Is there any other alternative to this?? I would not like to call the DataBind() method every now and then since my page has almost 8 - 10 hidden fields which are being bound to such constant values which are defined in Constants.cs

Awaiting for your valuable inputs.

Thanking you all in Advance

Regards
Pratik Shah

And what is the problem? The name of your control is hdnPosition not hiddenField. If you need to DataBind to multiple fields then call the Page.DataBind();

hi,

You can make the constant static, like
public static int position=10; // just as an example
And then use like

<asp:HiddenField ID="hdnPosition" runat="server" Value='<%= Constant.Position%>'/>

This should solve your problem. Smile | :)

Please mark this answer as good answer if you find this answer useful.

Thanks

Hello Shahriar,

Thank you very much for your immediate repsonse.

Unfortunately, using <%= Constant.Position%>' is not working. When viewed the HTML generated code in the browser it created something like <%=Constant.Position%>

Thanking you all in Advance

There are several ways to do this,You can access the control of parent window from popup.So you can assign the value to parent window.
For making it generic,Have some property in your popup usercontrol assign the id control on parent window to it and access it as you want.

on parent page

<script type="text/javascript">

function OpenPopup() {

    window.open("popup.aspx","List","scrollbars=no,resizable=no,width=400,height=280");

    return false;

}

</script>

on your user control

<script language="javascript">

function GetTextboxValue(val)

{

    // hardcoded value used to minimize the code. 

    // ControlID can instead be passed as query string to the popup window

    window.opener.document.getElementById("ctl00_ContentPlaceHolder1_TextBox2").value = val; 

    window.close();

}
</script>

Your user control should expose an event. Each page that uses the user control should listen for that event and in the handler for it set whatever values you need set.

Hi guys, tryn use the MS Sql LIMIT claus but not returning any values at all.
I tried both this but none return any values:

1. string query = @"SELECT * FROM [contact] LIMIT 0, 10 WHERE [user_id] = '" + userid + "'";
2. string query = @"SELECT * FROM [contact] WHERE [user_id] = '" + userid + "' LIMIT 0, 10";

I tried to use the OFFSET, but no luck either....
So far i have 30 sample contacts and would like to retrieve them 10 each
and none of the two statements are returning any record...
Anyone see my mistake here? please help...
Thanks,
Morg

As far as i know there is nothing like LIMIT in MS Sql Server.
You need to use other techniques.

you can develop an windows application which shows a messagebox in the form load reminding u of filling up the timesheet.And schedule that application using windows scheduler at your desired time.
