I am trying to do the following in a RadGrid with a MasterTableView and a Detail GridTableView:

1) User clicks EDIT on a parent row
2) Parent row goes into EDIT mode
3) Child rows, if any, also go into EDIT mode
4) Child rows are displayed automatically if parent row goes into EDIT mode

I have looked at and tried all of the currently posted methods for putting items (parent or child) into edit mode, including adding code to the PreRender event to add all of the child item indexes to the RadGridEditIndexes collection for the grid and rebinding without success. If I put the code in the PreRender event, the indexes are properly added to the RadGrid.EditIndexes collection but a straight call to RadGrid.Rebind doesn't render the child rows. If I, instead, call RadGrid.MasterTableView.DetailTables(0).Rebind, the detail rows are rendered but they are not in edit mode. (I have also tried adding my code to the ItemCommand and EditCommand events for the grid, but these do not work either...)

As a test, I commented out my PreRender code and added a GridEditCommandColumn to the Detail GridTableView. I am able to expand/collapse the parent, click edit on the parent and then click edit on its children - they all go into EDIT mode after their respective EDIT buttons have been clicked, so I know it's possible to get them to all show up in EDIT mode...

Any thoughts on how to accomplish this task is much appreciated, as I've spent 3 very unfruitful days trying to make it work. Thanks!

Notes: I have AllowMultiRowEdit set to TRUE for the grid, databinding is done server-side and I used the NeedDataSource event for databinding.

Here's my PreRender code:

    
            Protected Sub grdUsers_PreRender(ByVal sender As Object, ByVal e As System.EventArgs) Handles grdUsers.PreRender  
        
                    Try 
        
                        If (Me.ProjectID > 0) Then 
        
                            Dim editItems() As Telerik.Web.UI.GridItem = grdUsers.MasterTableView.GetItems(Telerik.Web.UI.GridItemType.EditItem)  
        
                            For intCounter As Int32 = 0 To (editItems.Length - 1)  
        
                                editItems(intCounter).Edit = True 
        
                                editItems(intCounter).Expanded = True 
        
                                If editItems(intCounter).HasChildItems Then 
        
                                    Dim customFields As Telerik.Web.UI.GridTableView = grdUsers.MasterTableView.Items(editItems(intCounter).ItemIndex).ChildItem.NestedTableViews(0)  
        
                                    If Not (customFields Is Nothing) Then 
        
                                        For Each fld As Telerik.Web.UI.GridItem In customFields.Items  
        
                                            grdUsers.EditIndexes.Add(editItems(intCounter).ItemIndex, grdUsers.MasterTableView.DetailTables(0).DetailTableIndex, fld.ItemIndex)  
        
                                        Next fld  
        
                                    End If 
        
                                    editItems(intCounter).SetChildrenVisible(True)  
        
                                End If 
        
                            Next intCounter  
        
                            If (editItems.Length > 0) Then 
        
                                grdUsers.MasterTableView.DetailTables(0).DataSource = Nothing 
        
                                grdUsers.MasterTableView.DetailTables(0).Rebind()  
        
                            End If 
        
                        End If 
        
                    Catch ex As Exception  
        
                        Throw New Exception("Error in grdUsers_PreRender() of module usrctrl_ProjectUsers: <br />" & ex.ToString)  
        
                    End Try 
        
                End Sub

[Solved] SelectedValue is null when using multi-combos and itemsRequested

The 5-15 build of RadControls appears to have a bug reading SelectedValue when in a multi-combo page that populates via itemsrequested

http://www.telerik.com/DEMOS/ASPNET/Prometheus/Combobox/Examples/Functionality/MultipleComboBoxes/DefaultCS.aspx

The server-side SelectedValue is null for the 3rd combo (the city in this example) when you selected a city.

I verified this by copying back the April build to verify it worked again, and then copying back the May 15 build to see if it breaks again, and then doing it once again for good measure!

I also shut down my browser, closed visual studio and restarted, and even copied back and forth the April/May dll's on a production server, so I'm pretty sure this is a real bug. This in on the 3.5 dll.

Old and new Telerik.Web.UI versions coexisting

I am using DotNetNuke with version fromn 2009 Q1. I have a third party DNN module which is giving the error below. DNN can only use one version of the assembly. Is there a way to make a DNN module use the newer Telerik assembly without recompiling the module?

Error Message:

How to disable some days of moth ???

Hi Everybody,

I've been finding a solution to this problem, but I havent solve this problem. I'm going to try explain this problem...

There is a aspx page where there is a calender control. The user select any dates, for example, the user selected theses dates: 9/11/2009, 12/12/2009 and 1/20/2009. Then the user clicks on next button, then this button redirects for another page. This new page there is another calender control, this calender control there are dates of period of time, like min: 1/1/2009 max: 1/1/2010.

But this calendar shows just dates that the user didnt select las page. So, that three date that the user selected above wont be to show them in this calendar.

Has Somebody ever had this problem? Can Anybody help me, please?

Thank you for attention,

Carlos

Prevent Custom Paging in RadGrid

Hi All,

I am trying to change the footer of the RadGrid where it says "Page Size = 5". Acutally I have set the property of Customer Paging allowed to false, but the Grid still shows the customer paging (so that the customer can change from page size 5 to 10, etc.)

I want to prevent that the customer can decide by himself which page size the Grid show have as any page size above 5 crashes my webpage (its too large then and jumps out of my HTML div).

How would it possible to solve this?

Any hints are very much appreciated.

Best wishes

Andi
