[Solved] Grid problem - work around?

[Chuck Harrington]

I have a situation that I wonder if anyone can suggest or point me to a solution that solves my problem.
I want to display the radcombobox so the user can select a date, which will return a set of records from a database.
The problem is that the grid does have any datasource until then and therefore does not display.
The combobox is in a commanditem template and does not display.  Would it be better to load the grid with dummy records(all zeros and nulls) or is there a better solution.
I just need to display the radcombobox.  Any suggestions will be appreciated.  The HTML is below.
<telerik:RadGrid ID="TimesheetGrid" runat="server" AutoGenerateColumns="false" EnableLinqExpressions="false" GridLines="None">

        <MasterTableView CommandItemDisplay="Top" AllowPaging="false" PageSize="15">

            <EditFormSettings>

Hi,

One suggestion is to bind the RadGrid using an empty DataSource for the first time when page loads. Please try the following code snipet.

C#:

protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            TimesheetGrid.DataSource = String.Empty;
        }
    }

Thanks,
Shinu.
