I am using the docking manager with about 8 document pane. There are about 10 to 50 controls on each of the pane, mostly labels, combobox and textbox.

I found that the performance is fairly slow. It takes about 2 seconds to switch between each tabbed pane. Is there anyway to improve the performance?

[Solved] Pin Bug in 2008 Q1

When I pin the first column in the grid using the context menu and then right click on the 2nd column header of the grid, I get the exception posted below.
No problem, when the first column pinned is not the first visible column in the grid.

Erwin

[Solved] How to Hide Zeros on bars

Hi,

I use horizontal Stacked Bars to show four different things about one person.
The display is Red Bar (Number centered in it), Orange Bar (Number centered in it),
Yellow Bar (Number centered in it) and Blue Bar (Number centered in it).

Work fine as long as noone has 0 as value.
Than it looks like
NO Red bar -- but a number (Zero) of the red value on the right side in the following Orange bar.
Or worse - Red==0 Orange == 3 Yellow == 0
So I get an orange bar with it's value in the center
AND 0 on the rigth as well as on the left :)

I build the graph from a generic list of objects.
So binding is simply done by setting datasource and the "Fieldnames" for the Series[x] values.

Is it possible to show no number if the bar is not visilbe == the value is zero?

Regards

[Solved] expand / collapse programmatically

I am trying to find a method that will allow me to programmatically expand all or collapse all detail lines in a RadWinGrid.. I really only need them to be expanded at the point when the gridview is populated.. I have tried using Me.gridview1.MasterGridViewTemplate.AutoExpandGroups = True with no success.. I believe this is because I am using a ChildGridViewTemplate for the detail line, and then linking it to the parent row via a GridViewRelation as opposed to using groups..

Any help would be appreciated!

[Solved] GridView 08/1 Bugs(?)

I'm playing around with Grid View 2008 and grouping, maybe I didn't understand the concepts yet but these are some of the problems I have:

After setting up the GridView with pre-set grouping, if the User changes the grouping, there are no longer any default group headers.

When loading directly from a Database Reader like this:

resultsRadGridView.MasterGridViewTemplate.LoadFrom(cmd.ExecuteReader());

Grouping does not work correctly.

After playing around with grouping, especially when placing two columns on the same level in the group panel, the group headers suddenly do no longer display correctly

When dragging a column from the group panel back to the header area, its size is extremely small and difficult to resize

Filtering does not work when grid is read only.

Context menu shows impossible tasks like "edit", when the grid is read only.
