Help - DataGrid - Specified cast is not valid. *Resolved*

[Tenebrosity]

I have been pulling my hair out over this and have yet to find a resolution. The code was working until I changed the bound until I started tweaking the DataGrid.

The ASP page code is:

<asp:datagrid id="DataGrid1" runat="server" GridLines="Vertical" DataKeyField="City" AllowPaging="True"
                PageSize="6" BackColor="White" CellPadding="3" width="80%" BorderStyle="None" BorderWidth="1px"
                BorderColor="#999999" AutoGenerateColumns="False">
                <SelectedItemStyle Font-Bold="True" ForeColor="White" BackColor="#008A8C"></SelectedItemStyle>
                <AlternatingItemStyle BackColor="Gainsboro"></AlternatingItemStyle>
                <ItemStyle ForeColor="Black" BackColor="#EEEEEE"></ItemStyle>
                <HeaderStyle Font-Bold="True" ForeColor="White" BackColor="#000084"></HeaderStyle>
                <FooterStyle ForeColor="Black" BackColor="#CCCCCC"></FooterStyle>
                <Columns>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:LinkButton runat="server" Text="Edit" CommandName="Edit" CausesValidation="false"></asp:LinkButton>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:LinkButton runat="server" Text="Update" CommandName="Update"></asp:LinkButton>&nbsp;
                            <asp:LinkButton runat="server" Text="Cancel" CommandName="Cancel" CausesValidation="false"></asp:LinkButton>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn>
                        <ItemTemplate>
                            <asp:LinkButton runat="server" Text="Delete" CommandName="Delete" CausesValidation="false"></asp:LinkButton>
                        </ItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn HeaderText="City">
                        <ItemTemplate>
                            <asp:Label runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.City") %>'>
                            </asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:TextBox runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.City") %>'>
                            </asp:TextBox>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn HeaderText="State/Country">
                        <ItemTemplate>
                            <asp:Label runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.State/Country") %>'>
                            </asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:TextBox runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.State/Country") %>'>
                            </asp:TextBox>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:TemplateColumn HeaderText="Contact Email">
                        <ItemTemplate>
                            <asp:Label runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.Contact Email") %>'>
                            </asp:Label>
                        </ItemTemplate>
                        <EditItemTemplate>
                            <asp:TextBox runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.Contact Email") %>'>
                            </asp:TextBox>
                        </EditItemTemplate>
                    </asp:TemplateColumn>
                    <asp:BoundColumn DataField="Active?" ReadOnly="True" HeaderText="Active?"></asp:BoundColumn>
                </Columns>
                <PagerStyle Font-Size="Smaller" HorizontalAlign="Center" ForeColor="Black" BackColor="#999999"
                    Mode="NumericPages"></PagerStyle>
            </asp:datagrid>

The DataGrid_Update Sub line of code that blows up:

Was working before my changes to the Datagrids look and feel:
        Dim City As String = Server.UrlEncode(CType(E.Item.Cells(2).Controls(0), TextBox).Text)
 
Tried this option as well:
        Dim city As TextBox = CType(E.Item.Cells(2).Controls(0), TextBox)
        Dim strcity As String = Server.UrlEncode(city.Text)

What am i doing wrong??

I have also tried this method.

Dim tbCity As TextBox
        tbCity = E.Item.Cells(3).Controls(0)
        Dim strCity As String = tbCity.Text.Trim

Any Ideas? I am so frustrated right now.

try giving IDs to the controls like
<EditItemTemplate>
<asp:TextBox ID="City" runat="server" Text='<%# DataBinder.Eval(Container, "DataItem.City") %>'></asp:TextBox>
</EditItemTemplate>


and then in the code

tbCity = directcast(e.Item.FindControl("City"),TextBox)

Lemme know if that works.
