Using A WebControl to edit records radgrid hierarchy

[Perry]

I have a Hierarchy grid with a using a Master TableView and one DetailTable that looks like this

 

<telerik:RadGrid runat="server" ID="PrintRadGrid" OnDetailTableDataBind="PrintRadGrid_DetailTableDataBind"
                                AutoGenerateColumns="false" OnPageIndexChanged="PrintRadGrid_PageIndexChanged" OnPageSizeChanged="PrintRadGrid_PageSizeChanged"
                                GroupPanelPosition="Top" OnUpdateCommand="PrintRadGrid_UpdateCommand" OnInsertCommand="PrintRadGrid_InsertCommand"
                                AllowPaging="true"  OnNeedDataSource="PrintRadGrid_NeedDataSource">
                                <GroupingSettings CollapseAllTooltip="Collapse all groups" />
                                <PagerStyle Mode="NextPrevAndNumeric" />
                                <MasterTableView CommandItemDisplay="Top" DataKeyNames="CaseId_Fk,LatentsId" HierarchyDefaultExpanded="false" RetainExpandStateOnRebind="true">

                                    </Columns>
                                    <DetailTables>

                                             </Columns>
                                            <CommandItemStyle BackColor="#AfAFa4" Font-Bold="true" Height="50px"
                                                VerticalAlign="Bottom" BorderColor="Black" BorderStyle="Solid" BorderWidth="1px" />
                                            <CommandItemTemplate>
                                                <div class="boldLabel"> Prints</div>
                                                <asp:Button runat="server" ID="lbAddPrint" Text="ADD NEW PRINT" CommandName="InitInsert"
                                                    CssClass="rgButtonText" CausesValidation="false" />
                                            </CommandItemTemplate>
                                            <ParentTableRelation>
                                                <telerik:GridRelationFields DetailKeyField="LatentsId_FK" MasterKeyField="LatentsId" />
                                            </ParentTableRelation>
                                        </telerik:GridTableView>

 

In the MasterTable View and the the DetailTable I want to use a web control for Inserting and Updating the records.  I have tried adding this code:

<EditFormSettings UserControlName="SubjectEdit.ascx" EditFormType="WebUserControl" PopUpSettings-Modal="false">
                                                <EditColumn UniqueName="EditCommandColumn1"></EditColumn>
                                            </EditFormSettings>

 

Put keep getting this  error :Telerik.Web.UI.GridTableViewCollection must have items of type 'Telerik.Web.UI.GridTableView'. 'EditFormSettings' is of type 'System.Web.UI.HtmlControls.HtmlGenericControl'.

What is the syntax to use the web control page and where within MasterTableView and DetailTableView do I put it?

Hi Perry,

The code snippet you have shared does not contain the entire setup, hence I am unable to identify the issue. Nevertheless I will show you a working example below:

<telerik:RadGrid ID="RadGrid1" runat="server">
    <MasterTableView EditMode="PopUp">
        <EditFormSettings EditFormType="WebUserControl" UserControlName="program.ascx">
        </EditFormSettings>
        <DetailTables>
            <telerik:GridTableView EditMode="PopUp">
                <EditFormSettings EditFormType="WebUserControl" UserControlName="program.ascx">
                </EditFormSettings>
            </telerik:GridTableView>
        </DetailTables>
        <Columns>
        </Columns>
    </MasterTableView>
</telerik:RadGrid>

Additionally to the Syntax, I would also suggest double-checking the project and ensure that no Control has the ID of "EditFormSettings" and also there aren't any custom classes with that name. They can conflict and produce the described issue.

Thank you very much Attila, this was exactly what I needed.
