I am currently manually databinding a RadGrid via server side. Although when I try to edit a record the Grid clears out, until I bind it again, then the item goes into edit mode. I'm not sure how to resolve this. Below is the code I have so far.

ASPX

<telerik:RadAjaxLoadingPanel ID="itemsLoadingPanel" runat="server" Skin="Vista" Transparency="30"></telerik:RadAjaxLoadingPanel>

<telerik:RadAjaxPanel ID="itemsPanel" runat="server" LoadingPanelID="itemsLoadingPanel">

<div>

<telerik:RadTextBox ID="itemSearchPSTxt" runat="server" EmptyMessage="PS #" />

<telerik:RadTextBox ID="itemSearchDescriptionTxt" runat="server" EmptyMessage="Description" />

<telerik:RadTextBox ID="itemSearchPartNumTxt" runat="server" EmptyMessage="Part #" />

<telerik:RadButton ID="itemSearchBtn" runat="server" Text="Search" OnClick="itemSearchBtn_Click"/>

<asp:Label ID="itemSearchErrorlbl" runat="server" Text="*You must input a search value" CssClass="error" Visible="false" />

</div>

<telerik:RadGrid ID="itemsRadGrid" runat="server" AutoGenerateColumns="true" AutoGenerateEditColumn="true" AllowPaging="true" OnItemCommand="itemsRadGrid_ItemCommand">

<MasterTableView CommandItemDisplay="Top" NoMasterRecordsText="No Records" EditMode="PopUp">

<CommandItemSettings ShowAddNewRecordButton="false" ShowRefreshButton="false" />

<EditFormSettings EditFormType="Template" PopUpSettings-Modal="true" PopUpSettings-Width="720px" CaptionFormatString="Edit Item">

<FormTemplate>
