Hi there

Here is my code:

    public string DateBegin
    {
        get
        {
            if (null != ViewState["DateBegin"])
                return (string)ViewState["DateBegin"];
            else
                return DateTime.Now.ToUniversalTime().ToString("MM/dd/yyyy") + " 00:00:00 AM";
        }
        set
        {
            ViewState["DateBegin"] = value;
        }
    }

and:

		if (!Page.IsPostBack)
		{
            DateBegin = DateTime.Now.ToUniversalTime().ToString("MM/dd/yyyy") + " 00:00:00 AM";
...

Markup:

    <asp:ObjectDataSource ID="sourceJobHistory" runat="server"
        ...">
        <SelectParameters>
            <asp:Parameter Name="startRowIndex"  Type="Int32" />
            <asp:Parameter Name="pageSize"       Type="Int32"/>
            <asp:Parameter Name="sortExpression" Type="String" />    
            
            <!-- problem is to pass the value into here -->
            <asp:Parameter Name="DateBegin"  Type="String" />    
   
        </SelectParameters>
    </asp:ObjectDataSource>

Any ideas? Thank you!
