How to Show Total Row Count of a Radgrid in the Header of a RadTabStrip

Question

I have an ASP.NET project in C# that uses a sqlDataSource. The project consists of a Telerik Radgrid, which sits on a RadTabStrip. I would like to know how I can possibly add the total row count of that grid into the Header Tab like seen in following image

Answer 1

I haven't worked with the RadTabStrip much so I don't know how to set that problematically; however, I've done something similar by displaying the item count elsewhere on the page. Perhaps this will help you achieve what you desire.

First, you'll should add a HiddenField into the page which will stored the number of items in the RadGrid.

<asp:HiddenField ID="HiddenField1" runat="server" />

Next, in the code behind, stick the number of items int he RadGrid into the HiddenField.

protected void Page_LoadComplete(object sender, EventArgs e)
{
    HiddenField1.Value = RadGrid.Items.Count.ToString();
{

Finally, on PageLoad, grab the value of the HiddenField and append it to the tab text.

$(document).ready(function () {
   var totalItems = $("#HiddenField1").val();
   $("#OpenTradesTab").Text("Open Trades (" + totalItems  + ")")
});

Hope this helps.

You can get an approximate answer by doing:

dgGrid.PageCount * dgGrid.PageSize
