Hi Mike,

This does not work.  If you type into the control it works fine. But setting  the .text property does nothing.

Me.ugcpImageLocation.Text = "c:\test\steve.txt"  

I'm using NetAdvantage 2010.2.

Best, Steve

Hi Steve,

I tried this out in a very simple case and I get the same results. Setting the text of the proxy does not do anything.

I'm not sure why that is, but I found that setting the Value on the grid cell will work and it also updates the proxy control.

this.ultraGrid1.ActiveRow.Cells["ImageLocation"].Value = "c:\test\steve.txt";

Mike,

Thank you for the work around. 

Best, Steve

Hi,

I'm not sure I understand what you mean. I tried this out with the sample you attached here and everything appears to be working correctly for me when I set the FormulaRowSourceIndex to RowIndex.

Hello Mike,

I added the above code. Now it works fine on the template row. However it stops working on the existing rows...

SO now i add on the template row and it shows the running total. After adding and saving it to the database and next time when i open it shows the total correctly, however it does not do the running total on the existing row.

Regards

Hi,

I've been looking into this issue and it turns out to be pretty complex.

To understand what's happening here, you have to understand some of the deep inner working for the grid and the CalcManager.

In simplest terms, the problem here is caused by the FormulaRowSourceIndex. This property on the grid's Override determines how the CalcManager deal with grid rows. It determines whether visible rows are included in a summary, for one thing, and also how relative references are handled.

By default, this property resolved to VisibleIndex, meaning that invisible rows don't count and are not calculated.

Obviously, the TemplateAddRow in this case is visible, but since it's a fixed add row, it has no meaningful VisibleIndex, so it is treated as not visible until it is committed and becomes a real row.

This begs the question of why the presence of a summary matters. The reason for this is also complicated, but basically, it's just a fluke of how the grid is implemented. In fact, the column in the Fixed AddRow probably should not be calculated when there is no summary, since it still has no meaningful VisibleIndex. It is getting calculated because when there is no summary, the calculations in the grid are deferred so that visible rows are calculated first and this goes directly to the UIElements on the screen.

So... if we were to "fix" this bug, the fix would be to stop the grid from calculating the column in the fixed addrow all the time.

That's obviously not what you want and such a fix would not benefit anyone, so we've decided not to do that unless there's a good reason.

In the mean time, you can very easily work around the issue by setting the FormulaRowSourceIndex to anything other than VisibleIndex.

ov.FormulaRowIndexSource = FormulaRowIndexSource.RowIndex

Hi,

I'm not sure why it's not working. It looks like this might be a bug in the grid. I'll ask Infragistics Developer Support to create a case for you and write this up for developer review.
