I am attempting to style a CartesianChartGrid's X and Y lines by setting the StrokeDashArray property.  However, when attempting to run the application, I receive an exception stating that the doublecollection must be unfrozen.  Here is the code snippet and I have attached the resulting exception message..

      <telerik:RadCartesianChart Width="400" Height="250">
            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:LinearAxis />
            </telerik:RadCartesianChart.HorizontalAxis>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis/>
            </telerik:RadCartesianChart.VerticalAxis>
            <telerik:ScatterPointSeries>

                            <Setter Property="StrokeDashArray" Value="4,2"/>

Hi,

This view basically displays Questions, Question Choices and selects or displays the answer as well. The Question Choices can be a Yes/No, MultipleSelect, MultipleChoice or FreeText.  The view has a RadGridView on line 260 and this grid has RowDetailsTemplate which displays question number and question text in a RadGridView . This RadGridView has has RowDetailsTemplateSelector which displays the Question Choices which is either Yes/NO or Multiple Choice or Free Text etc based on the  Question Type. This in turn calls the DataTemplates. Basically with this complex nested GridViews and Templates and the ModelView methods, the view takes at least 3 minutes to load 30 questions. 

How can I improve the performance of this View?

Your guidance is appreciated.

Thanks!

Hello, I'm implemented an AggregateFunction (CountFunction) in my GridView, but that decrease the perfomance of the loading drastically. Without the CountFunction, the Grid loads very fast, less than a second, and when i add the function, takes about 4-5 seconds to load the data, and, when I group a column and remove the group, it will take some seconds to load everything again.

Hi There,

Can anyone provide an example of how to catch connection 'drag & drop' events in a RadDiagram? I've bound all the connection related DnD events to a property handler but it get a hits very sporadically when moving the connections from one shape to another. The code is shown below. No doubt I'm doing something silly but I can't find any example anywhere in the docs. Any suggestions on how to get this to work are greatly appreciated.

Regards,

Eric G.

       // create some event handlers

       private void EdgeDragEnter(object sender, EventArgs e)
        {
            System.Diagnostics.Debug.WriteLine("drag enter");
        }

        .....

       // create some connections and wire them to the handlers

     var connection = new RadDiagramConnection() { Source = edgePair.Key, Target = targetInfo.node, ... TargetCapType=CapType.Arrow2Filled};
                connection.DragEnter += EdgeDragEnter;
                connection.DragLeave += EdgeDragEnter;
                connection.Drop += EdgeDragEnter;
                connection.BeginEdit += EdgeDragEnter;
                connection.EndEdit += EdgeDragEnter;
                connection.GotFocus += EdgeDragEnter;
                connection.ManipulationCompleted += EdgeDragEnter;

Hi,

Some of my grid cell values are unusually long. These are anomalies, so I don't want to make the affected columns wide enough to accommodate these anomalies. Instead, I'd like to use a tooltip to merely show the entire cell's value when its contents are cut off. How can I achieve this?

I am creating a Windows Service that needs to show status alerts to the user.  So, I'll put an icon in the system tray and post alerts when events happen.  Do you have a working example as to how this can be done?

Thanks for your help,

Hello

I use c# wpf telerik RadGridView and I have problem with Pasting. RadGridView`s cells contain my special custom type:

class Place

{

   int id;

   string name;

}

I need to get source cell in PastingCellClipboardContent to read Place.id:

private void radGridView1_PastingCellClipboardContent(object sender, GridViewCellClipboardEventArgs e){

if (e.Cell.Column.UniqueName == "Place"){

   //here i need source cell

}

How can I get it?

Thanks
