Hello,

I have performance problems with windows 8 theme.
When changing view, my radgridview takes more than  1.5s to appear.
The root cause is not my own code, I don't have this problem with other themes (windows7).

Anyone has had this problem?

Regards,

Laurent

Hi, I was wondering if there is a sample for the integration of RichTextBox in a DataForm?
I would like to use the RichTextBox as a replacement for a "normal" TextBox in a dataForm.

<telerik:DataFormDataField DataMemberBinding="{Binding Description, Mode=TwoWay}"

Label="Description:"

IsEnabled="True"

IsReadOnly="False"

Description="You can enter any information regarding this server in this field.">

<telerik:DataFormDataField.Content>

<telerik:RadRichTextBox x:Name="rtbDescription" Width="450" Height="200"></telerik:RadRichTextBox>

</telerik:DataFormDataField.Content>

</telerik:DataFormDataField>

I understand I'll have to capture certain events to keep the RichTextBox's document in sync with the bound property, and work with a FormatProvider to import/export the RichTextBox document into/from that property.

However, A sample would be much appreciated.

Thanks a lot

Hi,

for my scheduleview i create "GroupHaderResources" out of a database. These resources are employees and each employee is one group.
Grouping and filtering is running fine. if I create an appointment I set the group in my appointment dialog, ok. But is it possible to disable some
groups out of the grouphaderresource on entering the appointment dialog?

Thanks Regards

We need to create a custom layout algorithm class to be used for laying out nodes. I suppose a certain class needs to be derived, adding necessary logic to handle events such as "new level" etc. Do you have a sample app that demonstrates this technique?

The major reason for our need for a custom layout algorithm is that your algorithms fail for most trees when using custom nodes. It's usually something like 90% correct, but that 10% looks really awful.

More about this issue here:

This is what we have now:

Result: See treedown.png.
Wanted: See treedown_extended.png


UPDATE: Why not just give us the source code of TreeLayout.cs. That would help a lot!

Hi,

we use the RadDiagram as OrgChart. In your Example you have one CEO (Andrew Fuller) the next two Persons are President QA (Jeremy Boather) and President Dev. Dept. (Steven Buchanan).

Is it possible to have perhaps two CEO with one President in the next step? Or Two Presidents with one employee for each?
How must the xml file look like?

thanks

I am using the HierarchicalDataTemplate in my RadTreeView. The content of the data template is a grid and the grid has a context menu specified. The problem is the grid does not fill the RadTreeView cell (it seems to size to the content) so the context menu only displays if you click on the content, not anywhere in the cell. Is there a way to force the template to fill the cell or is there a better way to implement data template specific context menus?

An example of one of my data templates is:

My RadTreeView instance is:

Controlling the width of the datapoint plot area in RadCartesianChart

Hi

I am currently developing a simple bar chart showing a variable number of bar columns.

Now, I have used the PointTemplate property to set the bar columns at the same size regardless of the number of data points:



My problem is that when I have few data points I want the bar columns aligned to the left like this:

|    **     
|    **
|    **
|    **         **
|    **         **
|    **         **
|    **         **
|    **         **
|    **         **
|    **         **
|    **         **
|__**__,__**__,______,______,

But the chart control always distributes the data point plot areas evenly across the control space like this.

|            **     
|            **
|            **
|            **                         **
|            **                         **
|            **                         **
|            **                         **
|            **                         **
|            **                         **
|            **                         **
|            **                         **
|______**______,______**______,


I would really like to know how I can achieve the result on the top figure. How can I control the width of the plot area/container that holds the bar columns.
Either it must be totally obvious or it is simply not possible, as I cannot google my way to an answer.

Thanks
