Hello

In a release of WPF after 2015.2.728 (up to and including 2020.2.617) the ability to programatically set the DisplayIndex of a GridViewColumn was broken, in what seems to be a bug (it used to work fine, and I'm not sure what behaviour you could achieve with this bug in place).  I haven't pinpointed the release, as a lot of releases have happened during that time!

I've attached a simple example which demonstrates this bug, you just have to change the boolean constant in the code behind file from `false` to `true`, and you'll see that the group header no longer shows.  If you go back to release 2015.2.728 then this works, but now it only works if you set DisplayIndex to -1 (anything else causes an argument exception, as there's a mismatch to the number of columns, which makes sense).  If you don't have the header group then you can obviously change the DisplayIndex as required, but as soon as you do, it breaks the header grouping.

I'd post the code solution if I could, but it's pretty simple, you don't even need the public class in my code behind, that's there just to make the column group header obvious.

Thanks!

I have an application with a UserControl that contains a ListBox. The DataTemplate of the ListBox adds a button to each item. The ListBox is inside a BusyIndicator. If I set IsBusy to true from a command bound to a ListBox item the BusyIndicator does not show. If I set IsBusy from the constructor of the UserControl it does show. I am hoping you can tell me why it doesn't show from the command bound from the button.

Here is the xaml for the UserControl:

Here is the ViewModel code:

Here is the MainWindow xaml that hosts the UserControl:

This is the simple model I am using for testing:

I was able to get the BusyIndicator to show by calling a command bound to a button placed directly in the main content of the UserControl. But I really need this application to have the buttons on each ListItem if possible.

Don

Hello,

I set up my telerik nuget server according to your documentation.
But, I can't find the Ui.for.Wpf.45 package.

I just find the .Wpf.netCore package.

Can you help me.

Thank you

Hi,

I just started valuating RADGrdiView.

grid is binded to a datatable.

-When editing a cell in a row and then moving to the next row, is there a way to not automatically going into edit mode ?

-When on the last row, is there a way to move to the new(which is at the button) without pressing (Insert) or clicking on the new row using the mouse? meaning is it possible to navigate to the new row using the keyboard arrows for example.

Thanks

I've got a RadGridView that contains a RowStyleSelector and an InputBindings section. The RowStyleSelector has 2 conditions, one checking if a value is true and one checking if a value is false. In the false case, the only thing being done is setting the style to be based on the existing GridViewRowStyle with no changes. In the true case, the same happens but the background color is changed. When the false case is used, my InputBindings work fine. Once the true case is used, though, my InputBindings stop working. (Related, I also use behaviors via Microsoft.Xaml.Behaviors.Wpf, with one of them being to bind a command to the MouseDoubleClick event, and that event also stops firing when the above happens with the InputBindings.)

I had set a breakpoint in my code to see if it the command was getting hit and it would only be hit when the false case happened above.

In the below example, assume that Items contains a Cond boolean property:

I am using "UI for WPF Q1 2016".

I am creating a RadDocument and I set the font to Calibri prior to adding anything:

When I save as docx and open in Word, all is good.

When I open a modal dialog based on the RadRichTextBox, the ribbon bar says "Verdana".

When I save my multi-page document as PDF, the first page is obviously Verdana and the second page is obviously Calibri.

All I want is Calibri consistently throughout the document.

Thanks.

Hello,

We have a gridview filled with production steps. These production steps can be reordered. For this we have implemented a behavior like the "Reorder Rows" behavior in your examples.These productions steps have a status field, that describe the step needs to be done or is done. the production steps will have to be processed from top to bottom 

The steps with status done do not need to be dragged and dropped, and the steps with status not done should never be dropped before a step with status done.

Is there a way to disable drag and drop for specific rows or cancel drop on specific rows?

Best regards and thanks for your help

Hi,

Is there any way to display the new NotifyIcon in an application that doesn't have any window?

I tried putting it in app.xaml like this:

And then in App.xaml.cs:

But the icon does not display...

We are currently using Hardcodet.NotifyIcon.Wpf package for this, and with that component this kind of code works, but we would like to use the Telerik component instead!

Hi, I am new in telerik and (front-end). For my app I want to create dynamic Rad Cartisian chart ,fill it with scatter data points dynamically such that each data point should have predefined color. and store that dynamic created chart in tileview.

Problem is in assigning colors to each point. I would be very grateful if you can guide me in code.

  public RadTileViewItem CreateScatterPlotTile()
        {
            var chart = new Telerik.Windows.Controls.RadCartesianChart();
            var verticalaxis = new Telerik.Windows.Controls.ChartView.LinearAxis();
            var horizentalaxis = new Telerik.Windows.Controls.ChartView.LinearAxis();
            verticalaxis.Visibility = System.Windows.Visibility.Hidden;
            horizentalaxis.Visibility = System.Windows.Visibility.Hidden;

            chart.VerticalAxis = verticalaxis;

            chart.HorizontalAxis = horizentalaxis;

            ScatterPointSeries scatterSeries = new ScatterPointSeries();
            for (int i = 0; i < 100; i++)
            {
                ScatterDataPoint point = new ScatterDataPoint();
                point.XValue = xvaluelist[i];
                point.YValue = yvaluelist[i];
                scatterSeries.DataPoints.Add(point);
            }        
            chart.Series.Add(scatterSeries);
            var tile = new RadTileViewItem();
            tile.Content = chart;

            return tile;
        }  

Similarly I have color value list, How can I add colors from my list to each point.
