RadComboBox SelectionChanged Text Property Not Set Properly

When processing the SelectionChanged event for a RadComboBox, the Text property of the control is not yet set with the new text value. For example, we add a RadComboBox with the SelectionChanged event set to the following OnSelectionChanged.

private void OnSelectionChanged(object sender, SelectionChangedEventArgs e)

{

RadComboBox cb = sender as RadComboBox;

Trace.TraceInformation("cb.Text = {0}", cb.Text);

}

When we start typing in the Combo Box, the displayed text is always the Text value before the latest character. So,l when we type 1, cb.Text is null, when we type 2, the combo box displays "12", but cb.Text is 1.

How can we see the current value of the text box when the selection is changed?

enter "-0" into RadDatePicker will crash the application

Hi,

We are migrating some existing systems to WPF and when I try "-0" with the RadDatePicker, The whole application crashed immediately without further error message etc. Is this a bug of the control? Would this be fixed in the next patch or release?

PS. We are testing with version Q3 2009 SP1 and "-0" is one of the shortcut keys of our existing system.

Thanks,
John

[Solved] ApplicationMenu not closing with KeyTip

Hi,

I am running the following xaml:

<Grid><br> <telerik:RadRibbonView telerik:KeyTipService.IsKeyTipsEnabled="True"><br> <telerik:RadRibbonView.ApplicationMenu><br> <telerik:ApplicationMenu telerik:KeyTipService.AccessText="F"><br> <telerik:RadRibbonButton Content="New" telerik:KeyTipService.AltAccessText="N"/><br> </telerik:ApplicationMenu><br> </telerik:RadRibbonView.ApplicationMenu><br> </telerik:RadRibbonView><br> </Grid><br>

When I do "Alt+F", it opens the main menu like it should, but then if I press "N" alone, it clicks the button but does not close the application menu (and the access key disappears too). If I press "Alt+N", it closes the application menu promptly. My question is how do I close the application menu on just "N" alone?

Any ideas?

Disable add new row when grid is empty

Hello,

When I click in an empty gridview a new row is automatically created. How can I disable this functionality?

Because I need to do some validation first before a new row can be created in my scenario.

Thanks in advance.

[Solved] Confirmation dialog on bool Cell Edit (MVVM)

Hello.
I have boolean column in my grid with custom checkbox template:

<telerik:GridViewDataColumn Header="Custom Bool Column"

EditTriggers="CellClick"

DataMemberBinding="{Binding LabelReady, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"

HeaderTextAlignment="Center">

<telerik:GridViewColumn.CellTemplate>

<DataTemplate>

<Image Height="20" Margin="2" Stretch="Uniform">

<Image.Style>

<Style TargetType="{x:Type Image}">

<Setter Property="Source" Value="/red-cross.png"/>

<Style.Triggers>

<DataTrigger Binding="{Binding LabelReady}" Value="True">

<Setter Property="Source" Value="/green-tick.png"/>

</DataTrigger>

</Style.Triggers>

</Style>

</Image.Style>

</Image>

</DataTemplate>

</telerik:GridViewColumn.CellTemplate>

</telerik:GridViewDataColumn>

And I need to add a confirmation dialog on cell edit using MVVM approach, i.e. now when user double clicks on the image, the value is changed to opposite, how can I add a dialog, which will ask user if he really wants to change the value, and change the value in cell only if he press "Yes" ?

RadPivotGrid requires Windows Forms?

When installing RadPivotGrid references using your Nuget packages, I notice that the Nuget installer insists that my WPF project take a reference to System.Windows.Forms.

Why does a WPF control require WinForms-specific binaries?

Cell Selection feature

I've just discovered that the RadPivotGrid does not support cell selection. After searching your forums, I can see that this feature has been promised since Q1 2013 but not delivered as of Q! 2015.

Is there a realistic timeframe for the delivery of this feature? Not being able to select individual cells/rows/columns is a deal-breaker and will result in my project being forced to use DevExpress.
