Cannot Resolve: GridViewAlternateRowStyle

I have a RadGridView and I've used the article located at: http://docs.telerik.com/devtools/wpf/controls/radgridview/style-selectors/rowstyleselector for styling the row Foreground color. Everything works great except the Alternate Rows have the same color as the "regular" (non-alternate) rows.

I use the "BasedOn" attribute of the style to use the loaded theme (expression_dark) and I thought I would create a second style just for the alternate rows.

Here is the style code:

<Grid.Resources>

<my:WorkListStyle x:Key="WorkListStyle">

<my:WorkListStyle.ViewItem>

<Style TargetType="telerik:GridViewRow" BasedOn="{StaticResource GridViewRowStyle}">

<Setter Property="Foreground" Value="Yellow" />

</Style>

</my:WorkListStyle.ViewItem>

</my:WorkListStyle>

<my:WorkListAltStyle x:Key="WorkListAltStyle">

<my:WorkListAltStyle.ViewItem>

<Style TargetType="telerik:GridViewRow" BasedOn="{StaticResource GridViewAlternateRowStyle}">

<Setter Property="Foreground" Value="Yellow" />

</Style>

</my:WorkListAltStyle.ViewItem>

</my:WorkListAltStyle>

</Grid.Resources>

Then, in the RadGridView, I set these two options:

RowStyleSelector="{StaticResource WorkListStyle}"

AlternateRowStyleSelector="{StaticResource WorkListAltStyle}"

However, I get a run-time error when the xaml is parse on the "GridViewAlternateRowStyle" in the BasedOn attribute. Is there a different StaticResource I should be using? Thank you.

Readonly TextBox in CellEditTemplate filled with value Keypress

Dear Devexpress,

We are using your Gridview for WPF version 2015.1.225.40.

We have a problem :

for all columns we have a CellTemplate and a CellEditTemplate. The CellTemplate displays a value(sum) and is always read only.

The CellEditTemplate contains 2 textboxes were 2 separate values can be entered.
When those 2 Textboxes in the CellEditTemplate are read-only, there is still a way to enter a value., Why ?

How is it possible ? By selecting a column by mouse. Just one click on it.( It may not go in CellEditTemplate ). Then press a key (fe 2). Result => the readonly textbox contains now a 2 !

This may not happen.

Is there a solution to fix this problem ?

I have put the exemple code in a attached file. When the CanEdit1 property is set to false the problem occurs.

regards,
Gert

Overriding or removing an event?

I'm trying to override or remove the ability to click directly on the content of a DesktopAlert. My problem is that when you set the alert's content to a plain string, it acts as a link-button and upon clicking the text, it will close the window. This is a problem since there are certain DesktopAlerts that I don't want to be closed at all. I can set it as Enabled = False but then the dropdown menu and other parts of the alert quit functioning. This is all created from code behind so it is a little harder for me to set any properties or templates for it in XAML. I thought perhaps I should post in this forum and see if there is a way to not only remove the ability to click the content, but also to remove/override events in code-behind in general for WPF controls created server-side.

Dim mainAlert = New RadDesktopAlert() With {

.Header = "Messages",

.Content = "You have " & unreadCount & " new messages",

.Height = 75,

.Width = 300,

.IconTemplate = TryCast(Application.Current.FindResource("radIconTemplate"), DataTemplate),

.IconColumnWidth = 30,

.IconMargin = New Thickness(5, 10, 15, 0),

.CanAutoClose = False,

.ShowCloseButton = False,

.Tag = "main",

.ShowMenuButton = True,

.MenuItemsSource = GetDesktopAlertMenuItems

}

manager.ShowAlert(mainAlert)

Size of QRCode doesn't match Width & Height set on control

I want the QRCode size to match the Width & Height I specify on the control, but this doesn't work.
The size of the QRCode seems to be limited by Width & Height, but only changes when I set the Version differently.

I have tried to set the content alignment to Stretch also to no effect.

Can you please tell me how to do this?

Thanks,
Alan

</telerik:RadGridView.SortDescriptors>

</telerik:RadGridView>

TestResultRecords = new ObservableCollection<VolatileDynamicColRecord>();

m_TestRecord = new VolatileDynamicColRecord();

m_TestRecord["Sweep Voltage1-@2.5mA(V)"] = 1234

m_TestRecord["Sweep Voltage1-@2.8mA(V)"] = 5678

m_TestRecord["Sweep Voltage1-Item3(V)"] = 2.74353

TestResultRecords.Add(m_TestRecord);

Getting CommandParameter

Hi all,

I am trying to get the parameter out of CommandParameter on a button click. I got the parameter values in the EXECUTE method. The issue is the type of my parameter is not what I expected and also I am unable to cast it.

This is what I have as my parameter value.

Now, I can see the type of my parameter is Telerik.Windows.Controls.Primitives.SelectionChanger<object>, but I am not able to cast it in codebehind as I cannot see Telerik.Windows.Controls.Primitives.SelectionChanger.
Not sure if I am able to put my question correctly and completely. Please let me know if you need more information.

Regards,
Deepak
