Hi,
I would like to set the header Template to

                        <DataTemplate>
                            <TextBlock Text="{Binding}" >
                                    <TextBlock.LayoutTransform>
                                        <RotateTransform Angle="-45" />
                                    </TextBlock.LayoutTransform>
                            </TextBlock>
                        </DataTemplate>

I haven't found any solution.

Filter what can and can't be pasted

Hi,

I use the RadDiagram to show a program flow. It works well, but I'd like to filter which content can and can't be pasted.
For example, certain custom shapes should only occur once in the flow.
Is there a way to disallow some items to be pasted?

Kind regards

Getting Cell Name (A1, B1 etc)

Hello, I am filling my spreadsheet programmatically.

I need the cell "name" to use it in a formula.. For example:

string formula = "=SUM(" + worksheet.Cells[row, column].GETNAME() + ";" + worksheet.Cells[row, column + 1].GETNAME() + ")";

* This GETNAME method should return "A1", "B1", "C1", etc...

And then, set the formula value to another cell:

worksheet.Cells[row + 3, column].SetValue(formula);

Is this the best way of doing this? Remember that the variables 'row' and 'column' are set before in a logic that I have to use. So it can change.

Multi-Selection - Adjust single click behavior

Hi,

i'm trying to adjust the multi selection behavior of the RadGridView to fit our customers needs.

In a short: A single click should behave like control-click.

The grid is read-only and only used for selection & filtering purposes.
It has a couple of columns, including a GridSelectColumn on the left side.

A "mouse"-user needs to hit the small check box on the left side, otherwise the selection is lost.
Or needs to press "Control" all the time which is neither intuitive nor convenient.

Is there a possibility to change the default selection behavior of the GridView in such a way ?

Thanks in advance,

Thorsten Klingert

User Ability To Resize Chart Boxes

We presently have a .NET application which displays a diagram from an Oracle data source and a .NET program. Attached is a screenshot of the user interface with the diagram.

The goal is to provide the users the ability to dynamically resize the various 'rectangles' in the diagram, by dragging the horizontal and vertical lines. As an example, in the attached diagram page 2, we'd like to expand the TIG area from 33.33% to 50% by dragging the vertical line that separates it from General Reinsurance Corp.

As an example we would draw a vertical splitter line/object at the border and constrain the drag horizontally. When the splitter is dragged in either direction it sends a message to the adjacent object to resize and change value.

Question is are there any controls currently offered by Telerik out of the box that we could use to accomplish this?

MapItemsRequest - The calling thread must be STA, because many UI components require this.

Hello,

i try to use the MapItemsRequest with the MapPolyline and i have this issue: The calling thread must be STA, because many UI components require this.

public void MapItemsRequest(object sender, MapItemsRequestEventArgs eventArgs)

{

double minZoom = eventArgs.MinZoom;

Location upperLeft = eventArgs.UpperLeft;

Location lowerRight = eventArgs.LowerRight;

if(minZoom == 10){

//GET INFORMATION FROM URL (DownloadString - JSON and parse information)

var points = new LocationCollection();

foreach (var coord in feature["geometry"]["coordinates"])

{

points.Add(new Location((double) coord[1], (double) coord[0]));

}

var _polyline = new MapPolyline

{

Points = points,

Stroke = new SolidColorBrush(Colors.Brown),

Name = "id" + feature["_id"],

StrokeThickness = 3

};

FeaturesList.Add(_polyline);

eventArgs.CompleteItemsRequest(_trackList);

}

Running balance in a column

Hi:

I've pretty much gathered that this isn't supported natively, but surely there's a way to make it work with expressions or event handling. Or something.

Each row in my grid has a Credit column and a Debit column. It needs to have a Balance column that takes the net of the Credit and Debit columns in a row and then adds that value to the balance of all the rows before it. I suppose the quintessential example of this functionality would be a checkbook register. (

Credit - Debit - Balance

0 - 100 - -100

50 - 0 - -50

200 - 0 - 150

Thanks for the help.
