Group header and aggregates out of sync after collapse/expand

Koren asked on 25 Apr 2012, 05:32 PM

Some of my users are seeing the group headers and aggregate functions get out of sync in a grid after expanding and collapsing a couple of times. Groups will show the key and the details from that group but the aggregate results from another group.

This grid uses a group header template and the collapse all/ expand all functionality is in code using ExpandAllGroups() and CollapseAllGroups(). Is this a known issue? (I am having trouble duplicating this on my machine but I have seen it happen on other machines)

Here is xaml for the grid:

Hello Koren,

I used the code snippet you provide in order to reproduce the issue but I was not able to. I'm attaching my test project for a reference. Can you modify it in order to demonstrate the issue?

I have not been able to duplicate the issue on my machine either but I saw it happen on a user's machine. He sent me a screen print after the numbers got mixed up. I am attaching three screen prints. The first and second have the real data (you can see the Code and Accrual amounts). The MixedUp screen print has the screen after a couple of expand all/collapse all actions (you can see now the Code and details are right but the Accrual amount is from another record altogether). The Code comes from the group key. The cash, inv, accrual amounts come from the aggregates list.

We are using Q3 2011 (2011.3.1116.35). Do I need to update?

The grid is in a user control within a tab control if that helps.
Here is the style from the UserControl Resources:

<Style x:Key="EnterpriseStatusStyle" TargetType="TextBlock">

<Setter Property="Foreground" Value="{StaticResource LabelFontColor}" />

<Setter Property="FontWeight" Value="Normal" />

<Style.Triggers>

<DataTrigger Binding="{Binding Caption}" Value="Accrual">

</DataTrigger>

<DataTrigger Value="Equal">

<DataTrigger.Binding>

Sorry, I did not get back to this problem until today. I commented out some of the pieces of the aggregate functions to remove the custom function and the custom style. I am now duplicating this problem every time in my grid. For testing purposes, I am displaying the Header Aggregates along with a GroupHeaderTemplate of Aggregate Results. I am also displaying the cash total field in the grid so that I can verify the value. If you scroll all the way down and back up, it shows different results. It also shows different results when you collapse and expand. I cannot figure out what I am missing.
I included screen shots below.

Hello Koren,

We debugged the problem and it was related to the applied GroupHeaderTemplate. We managed to resolve it and the fix for it is part of our just released Q3 2012 binaries. The only thing you should set is RadGridView.GroupRenderMode="Flat". It is a new mode which improves significantly the performance in grouped scenario. I am attaching a sample project for a reference. Please give it a try and let me know in case of any problems.

It looks like the totals are fixed (on initial checking) when I use the GroupRenderMode=Flat. However, now I have two sets of totals because it seems to be ignoring the ShowHeaderAggregates value of False.

<telerik:RadGridView.GroupRowStyle>

<Style TargetType="telerik:GridViewGroupRow">

<Setter Property="ShowHeaderAggregates" Value="False"></Setter>

</Style>

</telerik:RadGridView.GroupRowStyle>

Do I need to set a different style to turn off the unwanted totals?

thank you!!!!

answered on 28 Nov 2012, 03:10 PM

Thank you. My display appears to be correct now.

However, a user did notice a problem with edit mode when the records are grouped this way (haven't seen it in other gridviews). If you click or F2 to go into Edit mode and then hit enter to move down, it seems to go out of edit mode randomly. You can move down a few rows without a problem (even across groups) and then it just switches to view mode when you hit enter so the focus is correct but you have to click to get back in to edit mode. It may be related to scrolling because it seems to happen when I get close to the bottom of my screen. Is this a known issue?

This issue reared its ugly head again. I tried to duplicate the issue in the test project but can't get all the conditions right (grid in user control which is in tab etc.). However, I tried on a whim to set my grid height to 500 to see what would happen. This fixes the problem. My current row as I get to the bottom of the grid now stays in sync and edit mode works. I'm not thrilled about hard coding the height of the grid but I will do that for now. Note: I had rowheight set to 27 for the older issue about viewing the bottom row but that did not fix this issue - it was Height. Is there a known issue with the grid scrolling/selected row? Anything I can do in my containers to avoid having to set the Height?

thanks! Sorry this is taking so long to debug.

grid-scroll.png

After playing with this for hours and getting the same scroll issue no matter what, I just tried the demos and was able to duplicate the problem.

In the GridView EditTemplates Demo, I did the following:
1. Dragged Name into the Group Panel
2. Using the mouse, I clicked once in the name column just to get focus and selected row on the first record.
3. Used the down arrow key to navigate down the grid. You will see in the picture that my focus moved over the header record but the selected record is one behind. It doesn't happen every time but I was able to duplicate the problem at least three times.

In my application when I arrow down (or move down after edit), the focus goes down but not the selection. This means that my record goes out of Edit mode and the user has to select the field again with the mouse or F2 to start editing again. On my screen, it almost looks like the scroll isn't going all the way down. If I use the right arrow, it moves the focus right and shifts up a tiny bit and then selects the record like it should.

Any ideas?

thanks!
