[Solved] "F2" should not select all text

Pressing F2 in a gridview/treelistview selects all of the text in the cell when it goes into edit mode. I am trying to make it work like Excel and just select the end of the text, but I can't see any way to do this. If I click in the cell to edit it, it the cursor goes where you click rather than selecting all.

Radbutton background color converters issue

Hi,

I would like to create and use a converter to change the background of a single selected button among the three buttons available. I don't want to handle a click event of the buttons and handle it from code behind and so tried different ways to create the converters, however it didn't work. Below I am providing a sample of my scenario. Any help would be greatly appreciated. Thank you.

<StackPanel Grid.Row="0" HorizontalAlignment="Center" x:Name="FirstRowControl" Orientation="Horizontal" Margin="232,0,233,0">
<telerik:RadButton Name="btn1" FontWeight="SemiBold" Margin="5" Content="Button 1" HorizontalAlignment="Left" VerticalAlignment="Top" Width="120" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button1</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
<telerik:RadButton Name="btn2" FontWeight="SemiBold" Margin="5" Content="Button 2" HorizontalAlignment="Left" VerticalAlignment="Top" Width="100" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button2</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>

<telerik:RadButton Name="btn3" FontWeight="SemiBold" Margin="5" Content="Button 3" HorizontalAlignment="Left" VerticalAlignment="Top" Width="180" Height="25" BorderBrush="Black" Command="{Binding UpdateTabCommand}" >
<telerik:RadButton.CommandParameter>
<models:Tabs>Button3</models:Tabs>
</telerik:RadButton.CommandParameter>
</telerik:RadButton>
</StackPanel>

Code in the VM:

public DelegateCommand<Tabs?> UpdateTabCommand
{ get; }

public Tabs SelectedTab
{
get { return base.GetProperty<PedpTabs>(defaultValueFactory: () => Tabs.Button1); }
set { base.SetProperty(value); }
}

public enum Tabs
{
Button1,
Button2,
Button3
}

public ClassVM()
{
UpdateTabCommand = new DelegateCommand<Tabs?>(OnChangeTabExecute);
}

private void OnChangeTabExecute(PedpTabs? selectedTab)
{
this.SelectedTab = selectedTab ?? Tabs.StateChanges;
}

protected override void OnPropertyChanged(string propertyName)
{
base.OnPropertyChanged(propertyName);

switch (propertyName)
{
case nameof(SelectedTab):
OnTabChanged();
break;
}
}

private void OnTabChanged()
{
switch (SelectedTab)
{
case Tabs.Button1:
MessageList = Messages2080;
break;

case Tabs.Button2:
MessageList = Messages2088;
break;
case Tabs.Button3:
MessageList = Messages2010;
break;
}
}

Thanks, Chand

[Solved] changing the Funnel filter icon

Hi
we are now in the process of choosing a WPF control set and Telerik is the front runner.
One thing we would like to know is whether it is possible to easily change the funnel-like icon for the filter at the column header of GridView control. Some of the managers want to make sure that we are not going to be stuck with it.
Thanks
Nick

Hello, I implemented the ZoomAndScrollSettings declaratively in my RadChart using XAML (You can see the code snippet in the attached file). The problem is that the Scrollbar to scroll or to zoom isn't displayed in the diagram. Have I forgotten something or did I do something wrong?

Disable Scrolling for LayoutControl

Hi, I have a hierarchy that looks something like this:

</LayoutExpanderGroup>

</LayoutGroup>

</RadLayoutControl>

My RadGridView has many columns and rows and so causes the entire <RadLayoutControl> to scroll. Is it possible to configure this view so that only the <LayoutExpanderGroup> that contains the <RadGridView> will scroll?

Any help would be appreciated.

RadCartesianChart how to hide vertical, horizontal or both scrollbars

I want to hide only the horizontal or vertical scrollbar. Is that possible ?

The only solution I found now is the following style :

<Style TargetType="telerik:PanZoomBar">

<Setter Property="Visibility" Value="{Binding Customization.ChartZoomMode, Converter={StaticResource ChartScrollbarVisibilityConverter}}"/>

</Style>

The problem here is that it is hiding both Scrollbars. Is there a option where I can decide which one I want to hide ?

How can I use correctly the above xaml in code behind ?

This is not working :

return new RadCartesianChart

{

//Resources = new ResourceDictionary()

//{

// {"HideScrollBarStyle", new Style(typeof(PanZoomBar))

// {

// Setters =

// {

// new Setter()

// {

// Property = ContentControl.VisibilityProperty,

// Value = Visibility.Collapsed,

// }

//},

HorizontalAxis = new CategoricalAxis()

{

LabelFitMode = AxisLabelFitMode.Rotate,

PlotMode = hasBarSeries ? AxisPlotMode.BetweenTicks : AxisPlotMode.OnTicks,

Title = Customization.XAxisName?.ToUpper(),

SmartLabelsMode = AxisSmartLabelsMode.SmartStep ,

LabelTemplate = new DataTemplate()

{

VisualTree = xAxisFormat,

},

//GapLength = 0.15,

},

VerticalAxis = this.HasMultipleAxis ? null : GetYAxis(),

SmartLabelsStrategy = new ChartSmartLabelsStrategy()

{

ShouldMinimizeConnectorConflicts = true,

},

......

.....

Optimize AStarRouter and FindExtendedRoute

Hi. I use AStarRouter and FindExtendedRoute. But if the diagram contains many items, it takes a very long time to load. This is especially noticeable when overlaying text on connectors. How I can optimize AStarRouter, for example, by reducing the number of search iterations? Or how I can catch a connection that takes a lot of time in FindExtendedRoute?
