Hey guys,

since i dont get it to work since 3 hours now i registered here in the hope you have a solution.

I have a GridView in my View:

The GridView Itemssource is bound to a DataView Property in my ViewModel.

The DataView is simply the .DefaultView of the Datatable i want to display.

With the data in my datatable i did some validation. In my validation i receive information which cells are invalid (rownumber and columnnumber/columnname).

Now my target is to set the style for the cells that are invalid (foreground color to red). But i cant get it working to get the GridViewCell based on the infos if have.

In some forum posts i saw code like MyGridView.Rows(index).Cells(anotherIndex) but the RadGridView dont have an accessable Row property for me.

I also tried some other things to get the cell like to get access the .Items Property or some attempts with the .ChildrenOfType<> method but nothing worked for me.

Is there any way to set the Cell-Style for a specific cell when bound to a DataTable or DataView? I cant use a cellstyle selector cause its not the value of the cell itself that is invalid, its only invalid in the context of row and column. The same value can be valid in another row or in another column.

You guys have any ideas?

Could i mark the DataView Cell in any way that i could react from a cellstyle selector on it or something like that?

Sirs,

I'm using RadVirtualGrid with a Custom DataProvider and I would like to format its columns where some columns would fit their width to their content, others to their cells' content, some columns would have their cells aligned to left, others to right, and so on.

I mean I want to apply a different style to each column in my RadVirtualGrid, however I don't know how to handle these styles.

Thanks in advance,

Hi,

Thanks.

Hi,

I have a project where we are creating recurring appointments in the ScheduleView. The date of the last occurrence is very important to the rest of the system. Is there a built-in way to determine the actual date of the last occurrence of a recurring appointment? I am not allowing the "no date" or "end after x occurrences" options, only the "end by" option. However, I can't rely on this date, because the last occurrence can occur before this date.FYI: I have a number of database queries that work based on the actual end date of an appointment, so this is why I need to calculate the date of the last occurrence.

Thanks!

when the window is display at a big monitor

I hide the RadRibbonView by click the expander  on the right ,when click a RadRibbonTab  header  the RadRibbonTab's width is not stretch to the screen' width

How to resolve this

I have three questions for my project. The output is attached.

1. The first one is the tooltip is not shown. I tried both DefaultVisualStyle and PointTemplate. This is the main thing so I post it in ToolTip sub-forum.
2. I want to line up the legend and Y axis. Which means the left side of colorful squares line up with the Y axis of the chart. I guess may  e ItemsPanel can be changed. 
3. Because I added margin to the series Margin="30,0". So the entire series shifts to the right. a little. Notice the right side the series is beyond the line scope. Is it possible to extend the line so the series is still within the line.

The converter is simple, it is just returning a string.

Thanks.

I want to add an apply button to the end of the "add new item" button when the NewRowPosition is set to e.g. Top.

After investigating which controls are involved, I tried to override the default style of DataCellsPresenter but the ItemsPresenter there seems to give me headache. Haven't used ItemsPresenter before so maybe the behavior is normal or it's modified elsewhere in your code.

Here's my modified style:

The ItemsPresenter seem to span over the button. I.e., the button is not visible. If I excplicitely change column's width from * to 128, the button is shown and the ItemsControl is smaller, but it is clipped after 128 pixels.

Is there another way to add a button to the end of the new item button? I want the user to be able to use the grid with only touch screen (i.e. no physical keyboard available). A cancel button would be needed also.

The optimal solution would be if the user taps elsewhere on the screen (not just the RadGridView control) but there's only one button on the screen ("Back") so that won't do. I.e., no other controls to transfer the focus to. Propably needs some sort of "global" click/tap listener and hit test class...
