Hi,

I have a window with one or more charts, sometimes i need the window to be in a small size so the charts have also a small size and the value labels are overlaped as you can see in the first image (overlaped.png).
I saw in another post that there is a property called IntelligentLabelsEnabled for Reporting controls, is there something similar in WPF? Or is there a way to accomplish this?

In the same project when I increase the size of the window the chart also look larger but value labels and axis labels remain the same size, is there a way to resize not only the chart but also the labels?

Finally I would like to know if there is a way to change the color of value labes, axis labels and axis lines, is it possible?

(chart1.png)

I am creating the bar series dynamically in the code behind.

Thanks in advance.

Converter called twice with MultiBinding

Since MultiBinding is not supported directly on GridViewDataColumns, I have the following:

<telerik:RadGridView ItemsSource="{Binding TestGridData}" Height="150" Margin="5" AutoGenerateColumns="False" ShowGroupPanel="False">

<telerik:RadGridView.Columns>

<telerik:GridViewDataColumn Header="StringValue">

<telerik:GridViewDataColumn.CellTemplate>

<DataTemplate >

<TextBlock>

<TextBlock.Text>

<MultiBinding Converter="{view:TestConverter}">

<Binding Path="StringValue"/>

<Binding Path="IntValue"/>

</MultiBinding>

</TextBlock.Text>

</TextBlock>

</DataTemplate>

</telerik:GridViewDataColumn.CellTemplate>

</telerik:GridViewDataColumn>

</telerik:RadGridView.Columns>

</telerik:RadGridView>

This works absolutely fine but I have to cater for the converter being called more times than I'd expect when editing the underlying collection. If I have 5 rows of data then the converter is called 10 times. The last 5 times are for the 5 rows of data but the first 5 times are for 5 sets of DependencyProperty.UnsetValue being passed into the converter.

Looking at the callstack, this seems to be caused by a call to ClearRow in the GridViewRowItem which is eventually hit as part of the ItemsSourceChanged event.

Can anyone explain why the grid needs to clear every row before assigning the new value? This doesn't happen with a non-multi binding, the converter is only called 5 times after an edit. Is it something to do with the fact that I'm using a CellTemplate?

Cheers! :)

RadDataForm exception

I just added a RadDataForm (as a UserControl) to my project for the first time. In the VS designer, everything looks fine. However, when the UserControl is instantiated (via a XAML DataTemplate), I receive the following exception:

System.Windows.Markup.XamlParseException - "Provide value on 'System.Windows.Markup.StaticResourceHolder' threw an exception."

with an InnerException of:

"Cannot find resource named 'DataForm_HeaderOuterBorder'. Resource names are case sensitive."

Any thoughts on what I'm missing would be appreciated.

Scrolling from another dialog

In my application I have a scenario where the user has one window open with the PDF Viewer control and they are looking at a pdf file then my application displays a modal dialog. The user needs to be able to still scroll up/down in the PDF Viewer while this modal dialog is open. I have given them some shortcut keys to scroll a page at a time (ctrl + pg up & ctrl + pg down) and then I send these commands to the control on the other window from the modal window. This works for scrolling by a page but a lot of the time they just need to scroll a few lines. Is there any API for the PDFViewer control that will allow me to send a command to scroll up or down a few lines?

Any help on this would be greatly appreciated!!!

Thanks in advance,
Lee

Table - Merge Cells Programmatically

Hi,

How do you merge table cells programmatically?

I'm creating a table via code as customer merge field, but I need to merge my header row with with all cells within the same row so that is spans multiple columns.

I'm using library version 2013.1.220.40.

Here's my code thus far (Sorry it's quite long):

Table table = new Table();

//Payment Details Title **

Span spanPaymentDetails = new Span("Payment Details");

spanPaymentDetails.StyleName = "styleTableTitle14";

Paragraph paragraphPaymentDetails = new Paragraph();

paragraphPaymentDetails.Inlines.Add(spanPaymentDetails);

TableCell cellPaymentDetails = new TableCell();

cellPaymentDetails.Background = Colors.LightGray;

cellPaymentDetails.Blocks.Add(paragraphPaymentDetails);

//BACS

Span spanBACS = new Span("BACS:");

spanBACS.StyleName = "styleTableContent14";

spanBACS.FontStyle = FontStyles.Italic;

Paragraph paragraphBACS = new Paragraph();

paragraphBACS.Inlines.Add(spanBACS);

TableCell cellBACS = new TableCell();

cellBACS.Background = Colors.LightGray;

cellBACS.Blocks.Add(paragraphBACS);

//Bank

Span spanBankTitle = new Span("Bank: ");

spanBankTitle.StyleName = "styleTableContent14";

spanBankTitle.FontStyle = FontStyles.Italic;

Span spanBankDetail = new Span("HSBC");

spanBankDetail.StyleName = "styleTableContent14";

Paragraph paragraphBank = new Paragraph();

paragraphBank.Inlines.Add(spanBankTitle);

paragraphBank.Inlines.Add(spanBankDetail);

TableCell cellBank = new TableCell();

cellBank.Background = Colors.Transparent;

cellBank.Blocks.Add(paragraphBank);

//Account Name

Span spanAccountNameTitle = new Span("Account Name: ");

spanAccountNameTitle.StyleName = "styleTableContent14";

spanAccountNameTitle.FontStyle = FontStyles.Italic;

Span spanAccountNameDetail = new Span("My Company Name");

spanAccountNameDetail.StyleName = "styleTableContent14";

Paragraph paragraphAccountName = new Paragraph();

paragraphAccountName.Inlines.Add(spanAccountNameTitle);

paragraphAccountName.Inlines.Add(spanAccountNameDetail);

TableCell cellAccountName = new TableCell();

cellAccountName.Background = Colors.LightGray;

cellAccountName.Blocks.Add(paragraphAccountName);

//Sort Code

Span spanSortCodeTitle = new Span("Sort Code: ");

spanSortCodeTitle.StyleName = "styleTableContent14";

spanSortCodeTitle.FontStyle = FontStyles.Italic;

Span spanSortCodeDetail = new Span("22-11-33");

spanSortCodeDetail.StyleName = "styleTableContent14";

Paragraph paragraphSortCode = new Paragraph();

paragraphSortCode.Inlines.Add(spanSortCodeTitle);

paragraphSortCode.Inlines.Add(spanSortCodeDetail);

TableCell cellSortCode = new TableCell();

cellSortCode.Background = Colors.LightGray;

cellSortCode.Blocks.Add(paragraphSortCode);

//Account No.

Span spanAccountNoTitle = new Span("Account No. ");

spanAccountNoTitle.StyleName = "styleTableContent14";

spanAccountNoTitle.FontStyle = FontStyles.Italic;

Span spanAccountNoDetail = new Span("xxxx xxxx");

spanAccountNoDetail.StyleName = "styleTableContent14";

Paragraph paragraphAccountNo = new Paragraph();

paragraphAccountNo.Inlines.Add(spanAccountNoTitle);

paragraphAccountNo.Inlines.Add(spanAccountNoDetail);

TableCell cellAccountNo = new TableCell();

cellAccountNo.Background = Colors.LightGray;

cellAccountNo.Blocks.Add(paragraphAccountNo);

//Cheque

Span spanCheque = new Span("Cheque:");

spanCheque.StyleName = "styleTableContent14";

Paragraph paragraphCheque = new Paragraph();

paragraphCheque.Inlines.Add(spanCheque);

TableCell cellCheque = new TableCell();

cellCheque.Background = Colors.LightGray;

cellCheque.Blocks.Add(paragraphCheque);

//Cheque Made Payable To

Span spanChequeMadePayableTo = new Span("Made Payable To:");

spanChequeMadePayableTo.StyleName = "styleTableContent14";

Paragraph paragraphChequeMadePayableTo = new Paragraph();

paragraphChequeMadePayableTo.Inlines.Add(spanChequeMadePayableTo);

TableCell cellChequeMadePayableTo = new TableCell();

cellChequeMadePayableTo.Background = Colors.LightGray;

cellChequeMadePayableTo.Blocks.Add(paragraphChequeMadePayableTo);

//Cheque Details

Span spanChequeDetail = new Span("My Company Name");

spanChequeDetail.StyleName = "styleTableContent14";

Paragraph paragraphChequeDetail = new Paragraph();

paragraphChequeDetail.Inlines.Add(spanChequeDetail);

TableCell cellChequeDetail = new TableCell();

cellChequeDetail.Background = Colors.LightGray;

cellChequeDetail.Blocks.Add(paragraphChequeDetail);

//Add Cells To Table Row

TableRow rowTitle = new TableRow();

rowTitle.Cells.Add(cellPaymentDetails);

table.AddRow(rowTitle);

TableRow rowDetails = new TableRow();

rowDetails.Cells.Add(cellBACS);

rowDetails.Cells.Add(cellBank);

rowDetails.Cells.Add(cellAccountName);

rowDetails.Cells.Add(cellCheque);

rowDetails.Cells.Add(cellChequeMadePayableTo);

table.AddRow(rowDetails);

TableRow rowDetails2 = new TableRow();

rowDetails2.Cells.Add(new TableCell());

rowDetails2.Cells.Add(cellSortCode);

rowDetails2.Cells.Add(cellAccountNo);

rowDetails2.Cells.Add(new TableCell());

rowDetails2.Cells.Add(cellChequeDetail);

table.AddRow(rowDetails2);

//Change Cell Padding

table.CellPadding = new Padding(5, 3, 5, 3);

//Create Document & Apply Styles

RadDocument document = new RadDocument();

RadDocumentStyles.AddStylesToDocumentRepository(document);

Section section = new Section();

//Add Empty Paragraph

Paragraph paragraph = new Paragraph();

paragraph.StyleName = "paragraphMailMergeTable";

section.Blocks.Add(paragraph);

//Add Table

section.Blocks.Add(table);

//Add Empty Paragraph

Paragraph paragraph1 = new Paragraph();

paragraph1.StyleName = "paragraphMailMergeTable";

section.Blocks.Add(paragraph1);

//Add Section To Document

document.Sections.Add(section);

document.MeasureAndArrangeInDefaultSize();

return new DocumentFragment(document);
