[Solved] Using ItemsControl with ExtendedDataConverter

I am creating a ToolTipTemplate in code based on this previous thread:
http://www.telerik.com/forums/programmtically-changing-mapshapereader-tooltip-when-using-a-custom-template

That works. However, the underlying MapShapeData represents information from an unknown number of values. Example:

Value 1

or maybe:

Value 1
Value 2
Value 3

etc.

Is it possible to bind an ItemsControl to list all these values without knowing in advance how many there are?

Expand hierarchy on mouse enter

I'm looking for a way to define a mouse enter event for the expand button on a hierarchy gridview. I have nested grids and a drag and drop functionality. I want to be able to start dragging and then mouse over the + and expand another row to drop into the child gridview. Is this a possibility?

Cannot set both DisplayMemberPath and ItemTemplate

I undestend that you some how with internal buisness logic set TextSearch.TextPath if developer set DisplayMemberPath value with ItemTemplate.
How you do it that with runtime code example?

I inherited your RadCombobox class

class EditComboBox : RadCombobox {
}

<Grid>
<controls:EditComboBox x:Name="ecbControl" telerik:TextSearch.TextPath="Description" />
</Grid>

How to dinamicly set
MyEditComboBox.TextSearch.TextPath="Description" ?

Here is my property

private static readonly DependencyProperty CurrentDisplayMemberPathProperty = DependencyProperty.RegisterAttached("CurrentDisplayMemberPath", typeof(string), typeof(EditComboBoxUserControl), new FrameworkPropertyMetadata(OnCurrentDisplayMemberPath));

private static void OnCurrentDisplayMemberPath(DependencyObject d, DependencyPropertyChangedEventArgs e)

{

var view = (d as EditComboBoxUserControl);

if (view == null)

return;

string value = (string)e.NewValue;

view.CurrentDisplayMemberPath = value;

}

[DefaultValue("")]

[Localizability(LocalizationCategory.Text)]

[Bindable(true)]

public string CurrentDisplayMemberPath

{

get

{

return (string)GetValue(CurrentDisplayMemberPathProperty);

}

set

{

SetValue(CurrentDisplayMemberPathProperty, value);

// Telerik.Windows.Controls.TextSearch.SetTextPath(this.ecbControl, value);

//this.ecbControl.DisplayMemberPath = value;

}

Place your code is settary of dependancy property.

Viewable portion of a RadDocument

Hello,

I am using the RadRichTextBox in a custom reporting solution in my application. I have a situation where the user has entered comments in rtf format in our application and I need to show these in a report. However, the comments may exceed the space on one page, so I need to detect the portion of the document that is visible within the bounds of the control and then split the document up over two or more pages, each with its own RadRichTextBox control.

When I check the CaretPosition at the end of the document the Y value on the Location property is less than the height of my control, but the text exceeds the bounds of the control when viewed.

Here is the code I am using:

DocumentPosition caretPos = null;

DocumentPosition endOfDocument = null;

var rtfText = myRtfText;

if (rtfText != null)

{

var provider = new RtfFormatProvider();

var radDocument = provider.Import(rtfText);

radDocument.SectionDefaultPageSize = new Size(maximumSize.Width, maximumSize.Height);

var radRichTextBox = new RadRichTextBox{Document = radDocument};

DocumentPosition tempPos = radRichTextBox.Document.CaretPosition;

tempPos.MoveToLastPositionInDocument();

endOfDocument = new DocumentPosition(tempPos);

caretPos = radRichTextBox.Document.CaretPosition;

caretPos.MoveToFirstPositionInDocument();

if(caretPos != endOfDocument)

{

var start = new DocumentPosition(radRichTextBox.Document.CaretPosition);

while (caretPos.Location.Y - start.Location.Y < maximumSize.Height)

{

if (!radRichTextBox.Document.CaretPosition.MoveToCurrentLineEnd())

break;

if (!radRichTextBox.Document.CaretPosition.MoveNext())

break;

}

if (caretPos.Location.Y - start.Location.Y > maximumSize.Height)

{

// Back up so the content fits within the range

radRichTextBox.Document.CaretPosition.MoveToLastPositionInPreviousParagraph();

}

var docSelection = new DocumentSelection(radRichTextBox.Document);

docSelection.SetSelectionStart(start);

docSelection.AddSelectionEnd(caretPos);

var docFragment = new DocumentFragment(docSelection);

var newDoc = new RadDocument();

var editor = new RadDocumentEditor(newDoc);

editor.InsertFragment(docFragment);

var rtfSegment = provider.Export(newDoc);

}

Also, attached is an image of the report with the control on it, clearly showing that there is text beyond the bottom of the control.

Any insight you could offer would be appreciated.

Thanks,

Peter

AggregateDescriptions

I have an AggregateDescriptions like this

<DataProviders:LocalDataSourceProvider.AggregateDescriptions>
<Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Count" AggregateFunction="Count" />
<Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Sum" AggregateFunction="Sum" />
<Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Max" AggregateFunction="Max" />
<Core:PropertyAggregateDescription PropertyName="Prize" CustomName="Min" AggregateFunction="Min" />
</DataProviders:LocalDataSourceProvider.AggregateDescriptions>

When using them in the RadPivotFieldList in the 'Value' -cell, they all show up as "Prize".
Is it possible to set a DisplayName or something like that?

And what about formatting money? Is it possible to set the decimals?

[Solved] Customize filter operators for DataFilter control

Hi,

We are considering whether to buy the WPF Telerik controls. However we have some difficulties to customize the data filter operators for DataFilter control.
For example, if i would like to only display IsEqualTo or NotEqualTo as operator selection only, what should i do?

Also, we have custom data type that might need to use a custom filter operator list. Can we pass in our own set of operator to the control? For example, some property like OperatorSource = {Binding OperatorList}?

Hope to hear from you soon.

Thank you.
