I have a grid with cell backcolor customized in the CellFormatting event (selected cells are highlighted as blue). Once the cells are not selected, I need to return the cell backcolor to its original color. I first tried setting e.CellElement.BackColor = Color.Empty;

 

 

 & Color.Transparent but this makes the cell as White instead of following the AlternateRowColor. After going through the documentation, I found that I can use CellElement.ResetValue(VisualElement.BackColorProperty). This seems to work better since it respects the AlternateRowColor. However, when I am using some of the Themes, it doesn't respect the ThemeColors. Is there something I am missing?

Hi,

We are currently writing an application that uses a frequently updated DataTable.

We tried out your grid view to display the data, where we used DataView as binding source. 

The nature of the application is to receive continuance updates from several sources, all coming in asynchronic fashion.

The DataTable update is synchronized, and only one thread at a time updates it.

When we are using Windows.Forms.DataGridView control binded to the DataView, it seems to work fine, but when using your control we get an Invalid Index Exception once we try to sort the columns.

The current rate and volume of the updates is about 80 records per source every five seconds, with up to 100 sources, and it is suppose to increase.

Your grid has been tested with three event sources.

Is there any way to update the grid DataSource, DataTable or DataView, in an asynchronic fashion,  meaning multithreaded, without having the need to overload the main thread using BeginInvoke ?

Are there any known design patterns for that manner ?

Hi, I am currently evaluating various docking controls for the company I work for and I am very impressed with the RadDock control. I have one small problem, however, that I believe is a bug:

I have a ToolTabStrip that has docked (Fill) inside it a ToolWindow called with a toolwindow:  PropertiesToolWindow. PropertiesToolWindow.Text = "Properties".

As I would expect  my toolwindow is displayed with the text "Properties" in the title bar and with no tabstrip visible.

Next, I drag another ToolWindow: colourToolWindow (colourToolWindow.Text = "Colour") and drop it onto my ToolTabStrip over NameToolWindow. This Docks (Fill) ColourToolWindow to the ToolTabStrip. The contents of Colour form are shown in the ToolTabStrip area. There is a toolstrip shown with the tabs "Colour" and "Properties". Colour is highlighted. So far so good. Except the title bar still has the text "Properties" where I would expect to see the text "Colour". This happens both at design time and run-time.

Thanks for your help.

Hello!

Is there a way to enable the grid for more excel-like behavior? At the very least I expect that when editing the data in a cell, the enter key ends and commits my edit.

Thanks,

hi all,

I was hoping to get some advise if a moveable/draggable panel contianer could be acheived for radcontrols in Winforms, i am trying to create a container control that can allow the user to drag or reorder a set of panels, like in google... Any tips on how to acheive this.

I have been able to move individual panels using the mousedown and mousemove events but i guess i want to reorder/align other panels with in the same container. Any advise would be appreciated! I am using Radcontrols for Winforms Q1 2009 atm.

cheers,
koms
