Hi,

I am starting with Telerik MVVM for WPF.

I would like to know how can I transform a Window Event (closing Event) in a DelegateCommand so that I can Drive in my ViewModel the event.

Thanks in advance

I'm replacing a plain textbox control that I had, with a RadMaskedNumericInput control, in a VS 2012 app. This control is to handle a client's social security number. However, in testing it I've found it doesn't exactly do what I want it to do. Here's the XAML:

With this, when the window first comes up, it looks like this: "___-__-___0". So if the user starts typing in a SSN, the problem becomes apparent. The 0, at the end of the control, starts getting pushed along. For example, suppose the user wanted to enter "123-45-6789" as a SSN. When they start typing what they get is, "___-__-__01". By the time they get to entering all digits from 1 to 9, in order, what they wind up with in the control is this: "012-34-5679". That is not what they want, but I don't know to make it work properly. Most likely I defined some property wrong, or left a property out. So, how do we achieve what we're trying to achieve?

Hi
I have a Radgrid and I have drag and drop enabled for this grid.
Whenever I try to drag a nonselected row and drop then all the other rows which are in between the dragged point and dropped point are getting selected. But I want just that one particular row  to be dragged.Did any one see this issue. I attached a image how it is being done.
Any help is much appreciated. These are the events I see.

Telerik.windows.controls.gridview.selection.selectiondrag.tryselectrowundermouse(bool scrolladjusted)
Telerik.windows.controls.gridview.selection.selectiondrag.tryselectelementundermouse(bool scrolladjusted)

I am handling these events
 DragDropManager.AddDragInitializeHandler(this.AssociatedObject, OnDragInitialize);
            DragDropManager.AddGiveFeedbackHandler(this.AssociatedObject, OnGiveFeedback);
            DragDropManager.AddDropHandler(this.AssociatedObject, OnDrop);
            DragDropManager.AddDragDropCompletedHandler(this.AssociatedObject, OnDragDropCompleted);
            DragDropManager.AddDragOverHandler(this.AssociatedObject, OnDragOver);

In the attached image I tried to drag no 3 and drop it at no 7. But all the other rows in between are selected while dragging.

Any help is much appreciated.

Thanks

Hi,

A property that was changed in code does not display in the cell it is bound to until the cell is clicked on twice.  The first click outlines the cell and the second click puts the cell into edit mode.  When in edit mode the new value is displayed.  Also, if a row is added the cell value is also displayed. What do I need to do to get the cell to display when the property is set.


private string columnAlias;
public string ColumnAlias 
{
get { return this.columnAlias; }
        set
        {
        if (columnAlias == value)
                return;
   
                this.columnAlias = value;
                Filter.EditWhereFilter();
                OnPropertyChanged("ColumnAlias");
}
}


 <telerik:GridViewDataColumn
            Width="15*" Name="ColumnAlias" Header="Alias" DataMemberBinding="{Binding ColumnAlias, Mode=TwoWay}">
</telerik:GridViewDataColumn>

<telerik:RadGridView
Name="radGridViewSelectedColumns" Grid.Row="1"
ItemsSource="{Binding CriteriaColumns,
Source={StaticResource criteriaColumns}}"  
        telerik:RadDragAndDropManager.AllowDrop="True" 
        SelectionMode="Extended" 
        SelectionChanged="radGridViewSelectedColumns_SelectionChanged"
        ShowGroupPanel="False"
        IsFilteringAllowed="False"
        ShowColumnHeaders="true"
        BorderThickness="0"
        EnableColumnVirtualization="False"
        EnableRowVirtualization="False"
        AutoGenerateColumns="False"
        CanUserFreezeColumns="False"
        CanUserResizeColumns="True"

        RowIndicatorVisibility="Visible">

Hello
I have strange "error" when using column grouping in xaml. The grouping is working, and I cannot find any issue with that however I don't like having binding errors in output window because that means that something is wrong.

I have flowing column:
 and following group description:
However during application start I can see following error:

System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Columns[DeviceTypeDescription]; DataItem=null; target element is 'ColumnGroupDescriptor' (HashCode=36687163); target property is 'Column' (type 'GridViewColumn')

When I go to the tab where grid is, grouping is working properly. Just for information. Data for taht grid is loaded only when I open tab not during application start.

Regards

Hi,

Is there a way to publish/subscribe messages so that I can implement a communication mecanism between different ViewModels of a View.

Does Telerik MMVM provide this kind of tool.

Thanks in advance
