Hello,

I'd like to restrict the size of my POI'S Datatemplate to be only shown in an explicit area so it won't get any bigger than this area.
Maybe a LocationRect would be given and my DataTemplate automatically expands and fills this Rect.

Can you tell me if there is a way to achieve anything similar to my requirements?

See a simplified version of my DataTemplate below:

<DataTemplate x:Key="ResizableTemplate">

<Grid x:Name="ParentRoot"

Background="Transparent"

telerik:MapLayer.Location="{Binding Path=Location}">

<StackPanel Orientation="Vertical" >

<TextBlock Text="{Binding Path=Title}" />

<TextBlock Text="{Binding Path=Description}" />

</StackPanel>

</Grid>

</DataTemplate>

VisualizationLayer:

<telerik:VisualizationLayer x:Name="POILayer" ItemsSource="{Binding POICollection}" ItemTemplate="{StaticResource ResizableTemplate}" />

Print to Non-Default Printer in Code

Is there a way to print the file from the code behind, but specify the printer to use? I know there is a default printer, but that doesn't work for me. I am using it to print labels. The label printer is rarely the default printer on client machines.

Thanks

Randy

Help with this Validation code

Okay, I am pulling my hair out and would like some help with this code. I took some code from this site to do cell validation. I don't have the current spreadsheet control and work will not pay for an upgrade, so I am trying to make due. Here is the code that does the validation I got to work (from another post):

private void ValidateCellValue(ICellValue cellValue)

{

bool isValid = false;

string stringValue = cellValue.GetResultValueAsString(CellValueFormat.GeneralFormat);

int intValue;

if (int.TryParse(stringValue, out intValue))

{

if (intValue >= MinIntValue && intValue <= MaxIntValue)

{

isValid = true;

}

if (!isValid)

{

MessageBox.Show("Not valid!");

Workbook workbook = new Workbook();

CellIndex activeCellIndex = this.worksheetEditor.Selection.ActiveCellIndex;

// Be carefull: SetValue() raises the CellPropertyChanged event.

this.worksheetEditor.Worksheet.Cells[activeCellIndex].SetValue(stringValue);

this.worksheetEditor.Worksheet.Cells[activeCellIndex].SetIsBold(true);

GradientFill greenGradientFill = new GradientFill(GradientType.FromCenter, Color.FromRgb(255, 255, 255), Color.FromRgb(252, 231, 0));

this.worksheetEditor.Worksheet.Cells[activeCellIndex].SetFill(greenGradientFill);

this.worksheetEditor.Focus();

}

As you can see, I can put a gradient fill behind the cell if the value is invalid. However, when I showed this to the users, they indicated it was to distracting and they just want the outline of the cell to be colored. So I found this code on the this site and have been trying to implement it:

private void InitializeRectangle(Rectangle rectangle, CellLayoutBox cellBox)

{

//rectangle.Fill = new SolidColorBrush(Colors.Red);

rectangle.Stroke = new SolidColorBrush(Colors.Red);

rectangle.StrokeThickness = 1;

rectangle.Width = cellBox.Width;

rectangle.Height = cellBox.Height;

Canvas.SetLeft(rectangle, cellBox.Left);

Canvas.SetRight(rectangle, cellBox.Top);

}

I have tried to pull this code in and replace the current gradient fill but keep running into problems. I would prefer to pass the cell to the InitializeRectangle method and have it paint the border red. Right now the method takes in a rectangle which isn't a problem, it is passing in the cellBox, how do I get the cell box in the validation method when the value is not valid?

Any help at all on this would be much appreciated.

Selection style

Hi,

I'm using the lastest version of Telerik and I also use the Office2013 theme. Actually, I create a custom UserControl which contain a RadScheduleView and I have some properties for different purpose. With the Office2013 theme, the highlighted items are not clearly visible on a laptop that's why I would like to know if it's possible to have a border of different color?!? At the same time, I would like to offer a property like "BorderSelectionColor".

I would like to cover the following situation:

- During a drag and drop operation, I would like to highligh + change the border color of the targeted appointments or slots cover by the source appointments

- I actually implemented a keyboard navigation pattern, the user can use the arrow keys to navigate through the slots or the appointements so I would like to highlight + change the border color of the slot or the appoinment where I am. The navigation mechanisim was already implemented but the highlight mechanisim not.

Thank's

Alain

Header values for RadPivotGrid

Hi,

I am using RadPivotGrid with my dyynamic selection of data and each time i get the datatable, i add appropriate values in LocalDataSourceProvider.RowGroupDescriptions, LocalDataSourceProvider.ColumnGroupDescriptions, LocalDataSourceProvider.AggregateDescriptions. I am using the following sample code to add values in these collection as example

var property = new PropertyGroupDescription();

property.PropertyName = item.DisplayName;

property.CustomName = item.DisplayName;

LocalDataSourceProvider.RowGroupDescriptions.Add(property);

All works fine. But in case of "RowGroupDescriptions", i want to display header values to let user know what they are. I have attached an image to describe the requirement.

here you can see that i have added "ID", "Status" and "TrackingNumber" in RowGroupDescriptions. "Priority" in ColumnGroupDescriptions and "Value" in ColumnGroupDescriptions. All looks good but i am unable to get header values for RowGroupDescriptions fields as mentioned in screenshot.

Please note that these fields are dynamic that is they can be changed according to the selection.

Any kind of help or suggestion is really appreciated.

Thanks

RadDateTimePickerStyle, in at least Office2013 theme, ignores Padding?

In the implicit styles inside Office2013 theme you will notice that the Padding is not used correctly in the control template and is completely ignored (see PART_DateTimeInput).

Can you fix this guys, or is this by design, and there is a workaround to set the padding of the control?
