GridView disapears after selecting Edit

[Guest]

Hi Everyone,
I have a gridview control with the following markup:
<asp:GridView ID="grdPOs" runat="server" AllowPaging="True"
AutoGenerateColumns="False"
BackColor="White" BorderColor="#CC9966" BorderStyle="None"
BorderWidth="1px"
CellPadding="4" DataKeyNames="ItemId" Height="68px" PageSize="5"
Width="642px">
<FooterStyle BackColor="#FFFFCC" ForeColor="#330099" />
<Columns>
<asp:BoundField DataField="Page" HeaderText="Page"
SortExpression="Page">
<ItemStyle HorizontalAlign="Right" />
</asp:BoundField>
<asp:BoundField DataField="CatalogId" HeaderText="Catalog #">
<ItemStyle HorizontalAlign="Right" Width="80px" />
</asp:BoundField>
<asp:BoundField DataField="ItemDescription"
HeaderText="Description" SortExpression="ItemDescription">
<ItemStyle Width="250px" />
</asp:BoundField>
<asp:BoundField DataField="Qty" HeaderText="Qty"
SortExpression="Qty">
<ItemStyle HorizontalAlign="Right" />
</asp:BoundField>
<asp:BoundField DataField="UnitPrice"
DataFormatString="{0:C}" HeaderText="UnitPrice"
SortExpression="UnitPrice">
<ItemStyle HorizontalAlign="Right" Width="70px" />
</asp:BoundField>
<asp:BoundField DataFormatString="{0:0.00}"
HeaderText="Total" InsertVisible="False" />
<asp:CommandField ShowEditButton="True" />
<asp:ButtonField CommandName="Delete" Text="Delete" />
<asp:BoundField DataField="POrderId" HeaderText="POrderId"
InsertVisible="False"
SortExpression="POrderId" Visible="False" />
<asp:BoundField DataField="OrderDate" HeaderText="OrderDate"
SortExpression="OrderDate"
Visible="False" />
<asp:BoundField DataField="ItemID" HeaderText="ItemID"
InsertVisible="False" SortExpression="ItemID"
Visible="False" />
<asp:ButtonField Text="Add" />
<asp:ButtonField Text="Cancel" />
</Columns>
<RowStyle BackColor="White" ForeColor="#330099" />
<SelectedRowStyle BackColor="#FFCC66" Font-Bold="True"
ForeColor="#663399" />
<PagerStyle BackColor="#FFFFCC" ForeColor="#330099"
HorizontalAlign="Center" />
<HeaderStyle BackColor="#990000" Font-Bold="True"
ForeColor="#FFFFCC" />
</asp:GridView>

The problem, is after clicking "Edit", the grid disapears. Has anyone seen
this. I'm still catching up on ASP.NET so please bear with me. Thanks for any
help.

You need to reload your grid in the edit sub

Hi Michael,

The markup that you posted does not show the method of databinding that you
use. Usually you would have a datasourceid value defined on the GridView
markup, but your code is not showing such a setting.

If you are databidning in the codebehind using a dataset, then you will have
to handle the GridView.RowEditing event to set the EditIndex property and
then re-databind.
