Hi,

I am trying to create a GridView with both Cell and CellEdit templates for one of the columns. The problem that I am experiencing is two fold:

1. If I bind the column AND the CellTemplate to the same property, I noticed that the IDadaErrorInfo indexer gets called twice per "Name" cell. This is a problem as the validation logic is not particularly straight forward and starts to create a performance issue once there are few dozen rows:

<telerik:GridViewDataColumn DataMemberBinding="{Binding Name}">
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Name, ValidatesOnDataErrors=True, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
    <telerik:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
            <TextBox Text="{Binding Name, ValidatesOnDataErrors=True, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

2. Removing the DataMemberBinding from the column and keeping it in the CellTemplate works fine when it comes to displaying the data, but does not seem to work with the IDataErrorInfo. I can see the indexer get called, however I do not see the validation error reflect in the UI. Which effectively means that the validation can only be shown in CellEditTemplates:

<telerik:GridViewDataColumn>
    <telerik:GridViewDataColumn.CellTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Name, ValidatesOnDataErrors=True, Mode=OneWay, UpdateSourceTrigger=PropertyChanged}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellTemplate>
    <telerik:GridViewDataColumn.CellEditTemplate>
        <DataTemplate>
            <TextBox Text="{Binding Name, ValidatesOnDataErrors=True, Mode=TwoWay, UpdateSourceTrigger=LostFocus}" />
        </DataTemplate>
    </telerik:GridViewDataColumn.CellEditTemplate>
</telerik:GridViewDataColumn>

What is the correct way of setting up Cell and CellEdit template binding to display IDataErrorInfo errors in both edit and non-edit mode at all times, while not having the IDataErrorInfo indexer getting hit twice as much as it should?

Thanks in advance,

Ross

Is there any sort of property on the tile that can prevent the tile from moving?

My tiles Position property is bound to a property in the entity the tile represents. I have tried putting logic in the property set to prevent changes if the position is 0, but that is preventing ANY of the tiles from changing position

    <Style TargetType="{x:Type telerik:RadTileViewItem}">
        <Setter Property="Position" Value="{Binding Path=DisplayIndex, Mode=TwoWay}" />
    </Style>

    public int DisplayIndex
    {
        get { return DisplayIndex; }
        set
        {
            if (m_DisplayIndex !=0 && value != DisplayIndex && value > 0)
            {
                m_DisplayIndex = value;
            }
            NotifyPropertyChanged("DisplayIndex");
        }
    }

Any ideas or insight? thanks!

Hi,

All I want to do is have the text of the chosen date right aligned in the textbox. I've tried all the different alignment and content alignment options I can think of and nothing works. Can someone please share the magic sauce?

Thanks .... Ed

Hello,

I am having difficulties in creating a RadCartesianChart Series Provider with a chart type of ScatterSplineSeries. In overview website (http://docs.telerik.com/devtools/silverlight/controls/radchartview/features/chartseriesprovider#overview), it states that to use ScatterSplineSeries, I need to use the ScatterSeriesDescriptor. But for some reason, the plot is not showing. I am just randomizing the data points in the viewmodel. If i remove the Style section, it is able to plot a Scatter Series. How do I go about to plot a Scatter Spline Series?

Hi,

I am trying to figure out how to show rows and/or columns in the PivotGrid whose cells are empty, so if I have a list of products from an OLAP cube selected, and there are no values for these products with the selected measure(s) - the grid returns no cells and no rows, so I only see the grand total line and nothing else. 

I would prefer all the selected data to be returned. Most pivot grids have an option to toggle this on or off, but I can't seem to find how to do this on the PivotGrid. 

Can someone please advise? 

Thanks

Hi to all,

I would add shape that has a big scale, for example 15.000 x 2.440 millimeters.

I don't use Diagram for its native scope, but I would use it for plane a big object. This because these one its measures stored into database.

I wouldn't convert value in little scale.

Can I change scale of diagram to use these values ?

Jump to other columns on edit mode

I need to evaluate the cell value of the column 1 and then jump to column 4.

If i change the currentcolumn on the cellvalidating or celleditended functions the Grid doesn't focus the column 4

Thanks,

I created a setup that closely matches the MVVM examples on http://docs.telerik.com/devtools/wpf/controls/raddiagram/populating-with-data/data-databinding. The RadDiagram is populated via a Graphsource. Peeking at the behind-the-scenes, it looks like the diagram wrap each item of the InternalItems collection in a RadDiagramShape to display it. How do I actually access those RadDiagramShape objects for each node so that I can manipulate it via code?
