Thanks for quick reply. I did the samething.  But that visually changes a lot. I need this first row to appear as normal first column or atmost column with merged cellstyle but definitely not as a separate band. I tried setting GroupByColumnsHidden = DefaultableBoolean.False but could not figure out how to get rid of GroupByRows. Also this ColA is not necessarily the first column, it could be any column in the table. 

please advice.
Thank you

 That's the constructor of the class. So in VB, you would do: 

 Public Sub New(ByRef FirstGridName As UltraGrid)
      Me.FirstGrid = FirstGridName
   End Sub

You are a lifesaver - it works beautifully!!!

Glad to hear it.

It probably doesn't matter now, but just so you know, I wrote up the NullReferenceException issue and it has been fixed internally. So it will be fixed in the next hot fix - just in case you want to use formulas instead of the CustomSummaryCalculator in the future. 

Mike,

That was so considerate of you!  Do you think one method has a faster response time?

Thanks again for everything!

Well, that depends what you mean by response time. CalcManager probably interferes less with the UI, since the calculations are done asynchronously. But probably uses more CPU time overall.

The ICustomSummaryCalculator is synchronous, but probably more efficient overall. 

It probably doesn't make all that much difference either way. :)

Mike,

I think same code what I have for the custom summary works just fine with a new grid. For some reson the old grid is having troubles with it.

For now , I am good.

Thanks a lot , Venkat.

Thank you very much for taking time to look into this.

You are right in saying summary formula line is commented but in the actual code its not.

If I follow you correct , scrolling down to the bottm should calulate the summaries but I dont see the correct summaries. SO I was running the same code in debugger , then I see that the custom class New method getting called but dont any other methods getting called and eventually summaries are not currect.

I am not sure why those beginSummary and other methods are not gettting called when step though debugger. Any clue ?

In the other post that I had posted the complete code.

I really appreciate your help on this as I am in crunch state of the project.

Thanks, Venkat.

Hi Venkat,

Well, the line of code you have here which adds the summary is commented out. :)

Assuming that's just a typo here in this forum post and that this line is not commented out in your actual code, then my next guess would be that the summary is not yet visible on the screen. The summaries don't get calculated until they are needed. So if your summary is at the bottom of the rows collection (which is the default), the calculation will not occur until you scroll down to the bottom of the rows and bring the summary into view.

Hi all ,

I followed this thread and wrote my customSummary class and used the Custom summaryType.Tried using the same but my methods inside the custom class didn't get fired. Ami doing anything wrong.

InterCompGrid3.DisplayLayout.Bands(0).Columns("CGDTH").AllowRowSummaries = AllowRowSummaries.True
        'InterCompGrid3.DisplayLayout.Bands(0).Summaries.Add("summaryCGDTH", SummaryType.Custom, New InterCompCustomSummary("CGDTH"), InterCompGrid3.DisplayLayout.Bands(0).Columns("CGDTH"), SummaryPosition.UseSummaryPositionColumn, Nothing)

Can anybody give a qucik pointer.

Thanks a Lot, Venkat.
       

I'm not sure off the top of my head, but if there is a way, it would probably be via the SummaryDisplayAreas property on the Override.
