Hello,
I have a RadAutocompleteBox and I'm looking for a way to select all text on focus.
I looked for SelectAll() method but there's not one. Is there a way to do this?

Thank you in advance
Best regards

PropertyGrid questions

Hello,

We are evaluating the PropertyGrid control and have a few questions.

1. When using Nested Properties, I am overriding ToString to display the child property values in the parent. However how do I get this string to update when the child properties are updated?

2. Is there a way to conditionally disable properties based on the values of other properties?

3. When using the Editor attribute with the EditorStyle.Modal option, is there a way to control the start position of the modal?

Thanks,
Hayley

How to make the point's color in a PointSeries changed dynamically

When I create a PointSeries chart, the point's color is determined at moment the chart is showing. But I want the point's color changed with the datasource's some content after the chart was shown.

So I make a new PlotInfo class shown as below, and I set DefaultVisualMaterialSelector bind to PlotInfo's ColorFlag, with a Converter.
Finally, the project doesn't work, the point's color didn't change when I modify the ColorFlag.
So does ChartView3D support this kind of abbility? And how can I get what I want?

public class PlotInfo : INotifyPropertyChanged

{

public event PropertyChangedEventHandler PropertyChanged;

public double XValue { get; set; }

public double YValue { get; set; }

public string ZValue { get; set; }

private string m_sColorFlag;

public string ColorFlag

{

get { return m_sColorFlag;}

set

{

m_sColorFlag = value;

if(this.PropertyChanged != null)

{

PropertyChanged.Invoke(this, new PropertyChangedEventArgs("ColorFlag"));

}

Always a tab and never a backstage ?

 private void RadRibbonView_SelectionChanged(object sender, RadSelectionChangedEventArgs e) { var ribbon = (sender as RadRibbonView); if (ribbon.SelectedItem is RadRibbonTab) { //DO STUFF } else if (ribbon.SelectedItem is RadRibbonBackstage) { //DO OTHER STUFF }

If I click on the backstage, this always triggers as a tab....which is causing me many problems.

Keep backstage open after an event within it ?

Hi,

We have an option to close our app in our Backstage panel:

var result = MessageBox.Show(unsavedChangesMsg, Properties.Resources.MessageBoxTitle_Confirmation, MessageBoxButton.OKCancel, MessageBoxImage.Question);

...if the user selected "Cancel" then the ribbon goes to last tab selected instead of staying in the backstage. The backstage isn't considered to be a tab it seems, so keeping it open is problematic it seems.

I've tried:

- Hiding all tabs.

- Unselecting all tabs.

- MasterRadRibbonView.SelectedIndex = -1;

- MasterRadRibbonView.SelectedItem = MasterRadRibbonView.Backstage;

- IsBackstageOpen = true; //databinding

...and a few other things, but when the screen comes back after the user exits out of the pop-up window, the last tab is loaded, when we want it to stay on the Backstage until the user selects a tab themselves.

RibbonTab IsSelected issue in RibbonView

Hi,

I have a RadRibbonView with RadRibbonTab inside it to display Module names.
The itemsource of RadRibbonView is set with my modules and these modules are converted to tabs at runtime using a converter to the ItemSource.
From the converter, I set the first tab as IsSelected= true and it set correctly and higlights the specific tab.
But the details/contents of that tab is not displayed.
Ie: OnSelectionTabChanged event doesn't fire in this case.
Where when I click a different tab, it works fine. but when i click the first tab again, it doesn't work.
When I checked using WPF inspector, i can see that IsSelected property of the first tab is always true even when i select a different tab.
any help?

am using 2013 Q1.
The same code was working perfectly whern i used rabribbontab. Now am converting this to radribbonview ince ribbontab doesnt exists in the new release.

Cheers
