CommandItemTemplate Question - Detail Tables Edit Indexes Count and How to Make a Detail Table Row Selected /Last Inserted Updated Row at All Times

[gc_0620]

Folks,

Using VS2010 with RadControls for Ajax Q1 2012.

I need some help with following issues:

1) For Example, while using Command Item Template, I can hide the the EditSelected Command Button based on RadGrid1.EditIndexes.Count of Master Table, How can I accomplish the same result  with Child Table (i.e. hide EditSelected Command Button based on RadGrid1.EditIndexes.Count of Child Table)?  Basically I do not want to show Child Table  EditSelected Command if there are no Child rows.

To get Child Table Edit Indexes count I tried to below line of code but is not working.

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>

Below is my Master/Detail Command Items Template.

<Mastertableview width="100%" commanditemdisplay="Top" datasourceid="SqlDataSource1" name = "Master"
       datakeynames="CustomerID">
           <CommandItemTemplate>
               <div style="padding: 5px 5px;">
                   Custom command item template for Master table

                   <asp:LinkButton ID="btnEditSelected" runat="server" CommandName="EditSelected"
                   Visible='<%# RadGrid1.EditIndexes.Count == 0 %>'><img style="border:0px;vertical-align:middle;"
                   alt="" src="Images/Edit.gif" />Edit selected Master Row</asp:LinkButton>

                   <asp:LinkButton ID="btnUpdateEdited" runat="server" CommandName="UpdateEdited"
                   Visible='<%# RadGrid1.EditIndexes.Count > 0 %>'><img style="border:0px;vertical-align:middle;"
                   alt="" src="Images/Update.gif" />Update Selected Master Row</asp:LinkButton>
                   '''
                   '''
               </div>
           </CommandItemTemplate>

                   <DetailTables>
                      <telerik:GridTableView DataKeyNames="OrderID,ProductID" DataSourceID="SqlDataSource3"
                               Width="100%" runat="server" CommandItemDisplay="Top" Name="Details">

                       <CommandItemTemplate>
                       <div style="padding: 5px 5px;">
                        Custom command item template for Child Table

                         <asp:LinkButton ID="btnEditSelectedChildRow" runat="server" CommandName="EditSelected"
                          Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>
                          <img style="border:0px;vertical-align:middle;"
                          alt="" src="Images/Edit.gif" />Edit selected Child Row</asp:LinkButton>

                          <asp:LinkButton ID="btnUpdateSelectedChildRow" runat="server" CommandName="UpdateEdited"
                           Visible='<%# RadGrid1.MasterTableView.DetailTables[0].EditIndexes.Count > 0 %>'>
                           <img style="border:0px;vertical-align:middle;"
                           alt="" src="Images/Update.gif" />Update Selected Child Row</asp:LinkButton>
                           '''
                           '''

                       </CommandItemTemplate>


                   </telerik:GridTableView>
                  </DetailTables>
                </Mastertableview>

2)  Below link from Telerik Documentation shows Making a Grid Row Selected at All Times (similar to WinForms grids). How can I accomplish the same result with Child Table (I have multiple Child Tables)?

3) Below Thread solution by Princy demonstrated Select Inserted/Updated row after performing command in Master Table. How can I accomplish the same result with Child Table (I have multiple Child Tables)?

Thank you very much for any help.

Any Suggestions?

For the time being, I would like to know is it possible  do not show Child Table EditSelected Command item from its CommanditemTemplate if there are no Child rows?

Thanks

Hello,

If I understand correctly what your requirement is you should check the Items collection count instead of the EditIndexes:

Visible='<%# RadGrid1.MasterTableView.DetailTables[0].Items.Count > 0 %>'>

Give this approach a try and check whether this is the desired functionality.

Kind regards,
