Resize Infragistics UltraDropDown column in UltraWinGrid

John Selkirk — Sun, 07 Jun 2009 18:43:39 +0000

One of the annoying things when using the UltraDropDown with a UltraWinGrid is that it refuses to resize the dropdown, and the columns in it, by default. This is at least in the Infragistics version that I a using (v8.3). After a bunch of searching + trial and error I managed to solve the issue.

The information to solve it ends up being on the Infragistics support forums but it NEVER cm up on any search that I ran. I essentially got lucky by finding it through a a set of links in forum entries.

Turns out of is a bug, go figure. The workaround plus then setting the width of the underlying column to that width (minus 2 so it doesn not show the scroll bars) worked like a charm.

Infragistics AfterCellUpdate event and when it is triggered

Yet another Infragistics post. I have been battling a defect where the event for a cell being updated was not being triggered until the the use placed the focus on a different cell.

It turns out that I should not be using the AfterCellUpdate event but rather the CellChange event instead.

The former is raised when focus is lost the latter is triggered EVERY time it is changed. Since I am wanting to know when the embedded CheckBox is clicked I am fine with that.

Infragistics first row in UltraWinGrid selected

The project that I am working on right now makes heavy use of Infragistics controls and in particular the UltraWinGrid. There has been a bug in the application for a while now that anytime the grid is refreshed the first row in the grid is also selected.

The weird thing is that in the code grid.Rows.Selected.Count == 0.

I have had other battles to fight so have left one alone. Until now.

It turns out that the row is not selected but is the active row.

There are two options, and I recommend doing both:

Set the ActiveRow appearance so that it does not look like it is selected. Instructions.

After setting a row as selected, make it the active row using grid.ActiveRow = row;

Hide Selection using Infragistics

One of the most annoying things that I have seen from Infragistics, an otherwise brilliant company, is the fact that when any of their controls lose focus the selected item is not longer selected!

This has been so annoying for a long time for me and I have finally found the property on the control that stops it from happening.

The property name is HideSelection and by default is set to true. Setting this value to false makes the selected item in that control (implemented by all Infragistics controls I think) keep the item selected when it does not have focus.

Simple thing. Yes. Bugged me for months. Definitely.
