RadPrintDocument from a grid wrong format when Right to left = true in grid

Hi, I have a grid that is set Right to left.
In one of the columns I can have negative numbers, so I had to set its string format as: {0:#,##0.00;#,##0.00-} in order to see the minus sing in the left side of the number (like this -100 instead of 100-)

when I print this grid, the negative numbers of this column are shown wrong (100-)

the only solution I found at the moment is to set the FormatString = "{0:n}"; before doing the print, and fter doing the print setting back the FormatString = "{0:#,##0.00;#,##0.00-}"; to look it well in the gridView.

any suggestions?

Check RadTreeNode check box without effecting selection

Is there a way to check or uncheck a RadTreeNode checkbox without effecting the selection? For our app, it's kind of handy that we can do both, but it's also useful that we check or uncheck without impacting the selection. Or possibly vice versa (current behavior) might be acceptable. In either case, ????

Setting default sort on columns to descending

Hi

I have checked the forums, but not been able to find a definitive answer on this.

We are displaying data that shows the top ranking products across a number of different criteria (columns). We only ever want to see these in descending order. I have tried using the SortChanging and SortChanged events, but with no success.

Can you assist me?

Embed custom palette in the default ContextMenu

Something like chartview-customization-palettes but not quite. I can define a custom palette simple enough. However, how do we embed it in the default Palettes ContextMenu?

RadGridView Sort Exception

I set up a SortDescriptor on my RadGridView using the example from http://www.telerik.com/help/winforms/gridview-sorting-setting-sorting-programmatically.html but I keep getting an exception thrown randomly:

System.NullReferenceException: Object reference not set to an instance of an object.

The descriptor is being used on a boolean checkbox column. Even though it throws the exception, the sort still executes. Any help would be appreciated. Thanks!

cant grip (grid.datasource as DataTable).GetChanges()

HI, I have a gridView (with DataTable as DataSource) and im trying to use the "GetChanges()" when the user change some data in the grid.

in order to use it I do this:
(grid.datasource as DataTable).GetChanges()

I found out that when I change one cell in the gridView, and then click out of that row , the GetChange() gives me the changes as it should

but

If I change one cell in the gridView, and then I click in another cell but in the same row. the GetChange() give me Null, like there where no changes.

The event grid_ValueChanged() is fired, but the (grid.datasource as DataTable).GetChanges() still giving null.

any solution?

Shortcuts and Accelerator keys For RadMenuItem Issue

Hi:
    I hope I can explain my problem clearly.

    When I add shortcuts and accelerator keys for RadMenuItem, I find some bugs or issues.

Step1: Add RadMenuItem "File". (Parent)
Step2: Add RadMenuItem "Open" (accelerator key is : O; shortcut is : Ctrl + Shift + G)
Step3: Add RadMenuItem "Add"  (accelerator key is : A; shortcut is : Alt + O)
Step4: Set "Add" is disabled.

Run the program, you can see the scene as the attachment below. Now, please enter "Alt + O",
the issues comes.....you can see it execute the "Open" function. Who can tell me why!!!!!
Is it mixed the shortcuts and accelerator keys ? is this a bug?
