View Issues gridview with childs

[gerbrand]

I've got something strange... 

My third child, when having only 1 row, it's not showing the row.

I took a screenshot of it

I'm not doing anything special in my code to make the grid. I've got it only with one record. When I have more records, I get to see them.

Hello gerbrand,

Thank you for contacting us. It is a known issue and we are working on it, but I cannot be more specific at the time being. Please excuse us for the introduced inconvenience. I have updated your Telerik points. I will write you back if we find a work-around.

I'm having the same problem, although it doesn't matter if my third child GridView has more than one row I still can't see them. The height of the third level grid is set so small you can't see the records.

Is there anyway to manually set the height of the child GridView?

Thanks,

Matt.

Hi,

I found a work around on another post on the forum.

This seems to do the trick

    Private Sub radGridView_ViewCellFormatting(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles radGridView.ViewCellFormatting
        If TypeOf (e.CellElement) Is Telerik.WinControls.UI.GridDetailViewCellElement Then
            Dim cell As GridDetailViewCellElement = TryCast(e.CellElement, GridDetailViewCellElement)

            cell.RowInfo.Height = 500
        End If
    End Sub

Just adjust the row height as you need to.

I hope the correct fix doesn't take too long to appear in a service release though!

Regards,

Matt.

Hi again,

Although the fix mentioned does fix the immediate issue. It is far from perfect. you end up with oversized rows and you seem to need to increase the row size by quite a bit to get it to work.

I was dissapointed to note that this has not been fixed in 2009 Q1 SP1. I would consider this an urgent fix as it does cause display problems.

How often do you release service packs for your control sets? Can you put this forward for a fix in the next one?

Thanks very much.

Matt.

Hello Matt,

I understand your concerns and we will try to address this issue ASAP. Currently we don't plan a service pack before the Q2 2009 release. However, if this is a show stopper for you we could provide an internal build that addresses the issue.

I have some concerns that this issue is different from the mentioned at the beginning of  this thread. Could you please send us a sample project that reproduces it. This will help us locate the issue and find a proper solution.

I am looking forward to your reply.

Hi Jack,

Thanks for your reply.  I have opened a support ticket attaching a sample project as I don't seem to be able to attach one here.

It shows the problem very well. I have included a bin folder with the Q1 09 version of the controls i'm using just to make sure i'm not compiling against an old version!

Thanks for you help, your support is the best in the business!

Regards,

Matt.

Below is the answer on my support ticket. Thought it might be useful to someone reading the thread...


Now I understand the issue. The child view height isn't changed when expanding collapsing child views. The height is measured only when expanding a view. We will take into consideration this scenario when developing our future releases.

You could use the ChildViewExpanded event to measure the correct size. Here is a sample:

    Private Sub RadGridView1_ChildViewExpanded(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.ChildViewExpandedEventArgs) Handles RadGridView1.ChildViewExpanded
        If e.IsExpanded Then
            If Not e.ParentRow.ViewInfo.ParentRow Is Nothing Then
                If e.ParentRow.ViewInfo.ParentRow.ChildRow.Height < 250 Then
                    e.ChildRow.Tag = e.ParentRow.ViewInfo.ParentRow.ChildRow.Height
                    e.ParentRow.ViewInfo.ParentRow.ChildRow.Height = 250
                End If
            End If
        End If
    End Sub

Thanks again Jack!
