Is there a way to determine if a Cell Value is being trimmed

Hi,

I would like to display a ToolTip for a GridView Cell only if the value of the cell is too large to fit within the column width? The ToolTip would be the complete cell value. Normally, the value shows an ellipse when it is trimmed but I can not find a property to indicate this.

Thanks,
Mike

ValueChanged

I have a form with a grid that contains just a combobox and I'm wondering what is the proper way to have that value stick, by stick I mean causing the CellValueChangedEvent, when I select a value in the list and then move to another control.

The relevent events that get fired are:

ValueChanging

ValueChanged

and then the next event is

Leave

I've played around with calling EndEdit, however I don't believe I'm calling it at the right point.

In the _Leave event I get the new row as

var newRow = lstData.CurrentRow as GridViewNewRowInfo, however the Cells["ComboColumn"].Value is null and this is becuase CellValueChanged hasn't fired yet.

Organisation chart collapse

Hi,

So I am building a dynamic organisation chart using RadDiagram. I have implemented the chart and the expansion of it. But now I would like to be able to collapse it. I have attached a photo to make it easier to explain.

So for example, if I press on 1.2.1 I would like to be able to collapse everything under. I have been able to collapse the shapes one level below only so in this case 1.2.1.1 and 1.2.1.2 using . it. But I am not sure how can I recurse for all the levels under it.

RadTileElement behavior problem when setting the CellSize

Hello,

I have a problem to handle RadTileElement when setting the TileGroupElement.CellSize property.

I create a TileGroupElement and set the RowCount Property to 3, then i add 3 RadTileElements.

I create a second TileGroupElement, set the RowCount Property to 3, the CellSize to 250;50 and then i add 3 RadTileElement.

When I launch the project, the two groups have different behavior.

On the first one, i can do everything, i can position RadTileElement where i want.

On the second one, the behavior is really different. If i move the RadTileElements the position management is a mystery, it is impossible to rearrange them in columns when they have move to row.

PdfViewer speed of showing

What can be the reason that some pdf (less size and less pages) loads much slower than others.
I'm using a FileStream to open the pdf and then I copy the FileStream to a MemoryStream and I LoadDocument with this MemoryStream.

I have a pdf ==> 1272 kb that exists of 41 pages
I have a pdf ==> 46 kb that exists of 1 page
But the pdf of 1272 kb is much quicker shown in the PdfViewer then the one from 46 kb?
What can be the reason of this??

Thanks
