Grid Scroll Bar Blowup Ver: 1.6.1.1

[Jim Jenkins]

Hello Group:

I have a Grid that Columns 1 thru 5 are hidden.

There are enough columns that there is a scroll bar across the bottom of the grid.

If scroll to the right the grid works fine.

If I then scroll to the left the grid fails within the “Set” method of ReflectScrolBar.cs.
The value that is passed in is 0.

The stack trace is attached.

Is this a bug, if not how do I scroll back to the first column?

Hi Jim,

I fixed yesterday a similar issue but I am not 100% sure if it is the same. If you open a support incident we can provide with the latest dlls that have this fix and then you can check if that also fixes the problem you see.

Thanks,
Stefan

Stefan,

we are experiencing a similar problem here with hidden rows. I see that there is a 1.6.1.1 build, that I seem not to be able to download anywhere, though. Is there a buld/service pack that we can use to check the fix you have applied?

Thanks in advance

There is a 1.6.1.4 private release that has this fix Stefan mentioned in it. If you submit a Direct Trac support incident, we can send you a download link.

Clay,

in the meantime we have tested 1.6.1.4 and the problem with hidden rows and scrolling still exists. These are our results:

1. When you scroll down by clicking on the arrow, the grid will not scroll to the last visible row.

2. When you scroll down by clicking in the scroll bar container (page-wise scrolling), we get an exception:

************** Exception Text **************
System.ArgumentException: '66' is not a valid value for 'value'. 'value'
should be between 'minimum' and 'maximum'.
at System.Windows.Forms.ScrollBar.set_Value(Int32 value)
at Syncfusion.Windows.Forms.ReflectScrollBar.set_Value(Int32 value)
at Syncfusion.Windows.Forms.ScrollBarWrapper.set_Value(Int32 value)
at Syncfusion.Windows.Forms.Grid.GridScroll.DoScroll(GridDirectionType
direction, Int32 nCell)
at Syncfusion.Windows.Forms.Grid.GridControlBase.SetTopRow(Int32
rowIndex)
at Syncfusion.Windows.Forms.Grid.GridControlBase.set_TopRowIndex(Int32
value)
at
....

Hope this helps.

Hi there

Is this issue resolved in any way? We are running the grid from version 1.6.1.5 but are still experiencing this problem.

Any help would be greatly appreciated, we are kind of dependent upon this scroll-functionality, so having it blow up is kind of a major issue for us...

You can download 1.6.1.8 from your support home page. I tried the problem posted in the initial post of this thread with that version, and could not see the exception.

With 1.6.1.8, if you still see the problem, could you send a sample showing it?
