Hey guys,

Hello,

I'm trying to format the Child Cells of a Hierarchical GridView via the CellFormatting event.

Here's the code I'm trying to use:


However, I'm finding that while the cellelement type sometimes is GridDetailViewCellElement, the columnindex is typically negative. In addition, I'm finding that the rowindex is out of range as well. Any help would be appreciated.

Thanks!

Hi,

after upgrading to the newest version of telerik controls I noticed that a couple of labels are not displayed as intended any more.
The text gets cut off though the label is definetely large enough to display the whole content.

i played around but I am not able to get the labels behaviour as it was before.

additionally I create labels dynamically on a form. suddenly the labels get rendered on a completly different location..
i changed the position where they get rendered... but why is this??

 -- suggestions how to fix this are appreciated.

thanks

best regards

Hi,
I'm developing a win form application using VS2005 and Teleric RadControls for WinForms Q1 2007.
I have inserted one docking Manager object in the forms with 4 docking panels and one tabbed document.

Now, when in VS I close the tab with form1.cs [Design], I receive the following error:
"The control Telerik.WinControls.Docking.AutoHideContent has thrown an unhandled exception in the designer and has been disabled.

Exception:
Cannot access to disposed object.
Object name: 'DockPanel'.

Stack trace:"
(there isn't stack trace)
The program works fine, error is only in the designer.
I have try to use dockingManager in various forms and this error occurrs only in some.. I can't find any solution.

Thanks for support!

Hi all,

We have implemented a master-detail hierarchical grid. The cell.image property of certain cells in the master grid, and also in the detail grid, is assigned an image depending on the value of some other cell in the same row. Note that not all master records have a corresponding non empty detail grid. Some do, because there is data to display bebeath them, and some do not because there is not any data to display beneath them. The cellformating event is used to assign the corrresponding images to the current cell as follows:

Private Sub FFAViewGrid_CellFormatting(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles FFAViewGrid.CellFormatting
        If e.CellElement.ColumnIndex = 3 Then
            Try
                Select Case e.CellElement.RowInfo.Cells(5).Value
                    Case "3"
                        e.CellElement.Image = FFAViewGrid.SmallImageList.Images(FFAViewIcons.UpTick_Green)
                    Case "2"
                        e.CellElement.Image = FFAViewGrid.SmallImageList.Images(FFAViewIcons.Minus_Green)
                    Case "0"
                        e.CellElement.Image = FFAViewGrid.SmallImageList.Images(FFAViewIcons.Minus_Red)
                    Case "1"
                        e.CellElement.Image = FFAViewGrid.SmallImageList.Images(FFAViewIcons.DownTick_Red)
                End Select
            Catch

            End Try
      end if
end sub

Initially the grid is displayed in unexpanded mode as in this picture: view picture  In htis example only the period columns labeled Q3-09 and Q4-09 have a non empty hierarchical child grid and have a value in cell(5) of the row to trigger the image property event. All other master rows have a zero value in cell(5) and hence they should not triger the image property event.

However, when you click to expand the master rows to see the detailed child grid for some reason randomly selected empty master rows are populated with cell images. This phenomenon repeats as many times as you expand and unexpand a master row, populating more random master rows with images when it should not. The picture of the undesired output can be viewed here: view picture and here: view picture

We have extensively tried to debug the cellformating event, only to notice that although the row index number was refering to an empty master row, one that  does not have any value in e.CellElement.RowInfo.Cells(5).Value  to trigger the code to display an image in cell(3), the value reported by the debuger for e.CellElement.RowInfo.Cells(5).Value was from another row and not from the one corresponding to the event.

We can only guess that this is a problem related to the fact that not all master records have a non empty detailed child grid. Do you have any other suggestions why is this behaviour caused and how it can be remedied?

Thank you in advance for your kind cooperation.

Regards,

George

I want to know about dock functionality with sample application,please suggest me

We have a large number of controls (be that a good or bad design principle) on a form, which seems to hog the CPU when the form is shown and not doing anything.  You can recreate the problem by looping around 200 or so insertions of a RadLabel and RadTextBox into a FlowLayoutControl. 

Is this a Rad controls problem or something else?

Best regards
