There is a lot of code below so I will try to explain first. I have a
Repeater and in the Repeater I have a Panel. In the Panel I have a
CustomValidator that needs to work with the value of a control that is
outside the Panel, but inside the Repeater.

What appears to be happening is that if the Panel is visible, it then calls
the CustomValidator - but for the CustomValidator in a different row - that
is hidden.

Here is my code:
protected void ValidateMapDatasource(object sender, ServerValidateEventArgs
args) {
    CustomValidator vldtr = (CustomValidator)sender;
    DropDownList lst = (DropDownList)vldtr.Parent.Parent.FindControl("mapType");
    if (lst.SelectedIndex != 4)         {
        args.IsValid = true;
        return;
    }
// should come to here as SelectedIndex == 4 if the Panel is visible - but
returns above because it gets the lst for the next row.

Here is the aspx:
                            <asp:Repeater ID="mapRows" runat="server"
OnItemDataBound="MapDataBind">
                                <HeaderTemplate>
                                    <table width="100%">
                                        <tr>
                                            <th>
                                                <asp:Localize ID="Localize9" runat="server" Text='required'
/></th>
                                            <th>
                                                <asp:Localize ID="Localize10" runat="server" Text='<%$
Resources:Header, VarName %>' /></th>
                                            <th>
                                                <asp:Localize ID="Localize11" runat="server" Text='type' /></th>
                                            <th>
                                                <asp:Localize ID="Localize12" runat="server" Text='description'

                                        </tr>
                                </HeaderTemplate>
                                <ItemTemplate>
                                    <tr>

                                                <asp:TextBox ID="mapSelect" runat="server" Columns="50"
Text='<%#Eval("Select")%>'></asp:TextBox>
                                                <asp:DropDownList ID="mapSelectDatasource" runat="server" />
                                                <asp:CustomValidator ID="CustomValidator2" runat="server"
OnServerValidate="ValidateMapDatasource"
                                                    ControlToValidate="mapSelectDatasource" Text="Please select a
datasource." />
                                            </asp:Panel>
                                        </td>
                                    </tr>
                                </ItemTemplate>
                                <FooterTemplate>
                                    </table>
                                </FooterTemplate>
                            </asp:Repeater>

Any ideas?

Hi David,

I have done some test, but wasn't able to reproduce the issue you mentioned.

First, I don't think the FindControl("mapType") is returning the wrong
DropDownList, can you verify that, for example: change the found
DropDownList's SelectedIndex in the validate event.

During my test, if I bound the repeater in every postback, the state of the
DropDownList will be lost and the SelectedIndex will always be 0.

Could you please post the complete webform so that I can test that? Thanks.

Sincerely,
