Hello,

I am using VS Professional 2015, DevCraft Ultimate version 2016.2.613, UI for WPF RadListBox.  Using Office2013 Theme, I wish to override the color of a RadListBox's selected RadListBoxItem.  I also want to override this background color for mouseover.  Currently these are an orange color and I want to change that.  My understanding is that the RadListBoxItem control template has a border named "SelectedVisual" and I need to override its background color.  Maybe something similar for mouseover? (haven't got there yet).  My problem is that I can't figure out how to do any of this using Expression Blend 2015.  I'm on the Objects and Timeline pane and when I right click on my RadListBox I don't see an option for "Edit Additional Styles" which I think would get me to the RadListBoxItem's style.  I do see "Edit Additional Templates" but nothing I try around that option is getting me to the "SelectedVisual" border.  I would welcome any info on 1) how to do this in Blend or 2) any recommended alternative method to override RadListBoxItem's selected and mouseover background colors.  Please see attached imagesto better visualize what I'm trying to do.

Thanks,

Chris

I am using WPF. I want to Export the selected Rows from the RadGridView to Excel. I have managed to export all the rows to Excel, but if the user makes a selection I want to export only the selected rows to Excel. Here is my code below, I just need ti implement the TODO section. Can someone help ?

hi dear supporters,

i have used the connection content  and connection points to route the connection.

now, the connection content is positioned in the middle of the connection but i need to position it in other positions.

the image is attached.

my code is also here.

how can i get the needed position of the connection content.

        private void diagram1_ConnectionManipulationCompleted(object sender, ManipulationRoutedEventArgs e)
        {
            var image = new System.Windows.Controls.Image() { Source = new BitmapImage(new Uri("components/" + "conn"+ ".png",UriKind.Relative)) };
            System.Windows.Point startPoint= e.Connection.StartPoint;
            System.Windows.Point endPoint= e.Connection.EndPoint;
            double deltaX = Math.Abs(endPoint.X - startPoint.X);
            double deltaY = Math.Abs(endPoint.Y - startPoint.Y);
            image.Stretch=Stretch.Fill;
            image.Width = 0.8*Math.Max(deltaX,deltaY);
            image.Height = 5;
            TextBlock txt = new TextBlock();
            txt.Text = strSelectedComponent;
            StackPanel stpanel = new StackPanel();            
            stpanel.Children.Add(txt);
            stpanel.Children.Add(image);            
            Viewbox viewBox = new Viewbox() { Stretch = Stretch.None, Margin = new Thickness(-4) };
            viewBox.Child = stpanel;
            e.Connection.ConnectionPoints.Add(new System.Windows.Point(endPoint.X,startPoint.Y));
            e.Connection.Content = viewBox;
        }

Hi, I tried to follow the examples in this thead but I can't get it working. Can someone show me ho to set the backgroud of the rows where the columns Quantità and QtaPrelevata have the same value?

Hi all,

I am working on a WPF application using Telerik and coded in C# .NET.
My following question is over a WPF page using the “Code behind” model to implement the logic of the page.

Currently, I have a <telerik:RadGridView> for which the source is the DefaultView of a DataTable containing 365 columns (or 366, it depends on the number of days in a year).

But I am facing an issue :

The source of the RadGridView is a 365/6 columns DataTable (DefaultView).

It does not seem that all the columns are loaded at the begining.
I mean that I have to scroll 3 times to the end of the scrollbar to make all the 365/6 columns appear . => This could be another issue, but it is my opinion.
I would like to know how to load all that columns at once ?

Any help or tip will be much appreciated :)

I have a fairly complicated application that includes a RadDataForm that contains a TextBox that is supposed to allow a user to type multiple lines. The TextBox has TextWrapping="Wrap" and AcceptsReturn="True", but it doesn't work, of course, because RadDataForm binds the return key, and commits the form, regardless of what type of field has the focus.

So I wrote a simple DataFormCommandProvider:

Stick this in a resource, and set the form's CommandProvider, and suddenly I can enter multiple lines in the TextBox:

And, of course, something else breaks.

I have a pair of save and cancel buttons, outside the form, that set RadDataFormCommands.CommitEdit and RadDataFormCommands.CancelEdit.

When I do not have the CommandProvider set, these work fine. But when I do, they're disabled. Both of them are disabled, even the Cancel button, which isn't ever supposed to be disabled.

This should be simple. What am I doing wrong?

I have a RadDataForm, and need to be informed when the form's validation status changes.

What I thought I could do was to listen to RadDataForm.ValidationSummary.Errors.CollectionChanged, but unfortunately, even as late as RadDataForm.Loaded, RadDataForm.ValidationSummary is null.

Is there some event that RadDataForm fires when its validation status changes?

Or some event that RadDataForm fires after its ValidationSummary has been created?

Hello,

I'm using a GridView with data bound via VirtualQueryableCollectionView (like in this example: http://docs.telerik.com/devtools/wpf/consuming-data/using-data-virtualization).

When a user double clicks a row, I show a detail form and after the user is done editing and closes the form, I reload the data to reflect the changes made by this and other users.

After loading the data, I would like to highlight the row the user just edited.

When the GridView is bound do a normal list of data, I can easily do that by querying for the object in the loaded data and then setting

gridView.SelectedItem = x

but since switching to the VirtualQueryableCollectionView, this doesn't work any more.

Is there any way to select a data item / row in a GridView that uses VirtualQueryableCollectionView as DataContext?

Hi all,

I am working on a WPF application using Telerik and coded in C# .NET.
My following question goes over an ASP .NET page using the model “Code behind” to implement the logic of the page.

Presently, I have a <telerik:RadGridView> for which the scrollbar moves at the same time as the RadGanttView chart scrollbar.

But I am facing to an issue : 

I would like to get the MinorTick actual width and apply it to the RadGridView columns.

I edited a copy of the template of the GanttView in order to find (I hoped) the width value of the MinorTick. I did not find it.

I accessed the MinorTick's Interval and I tried to apply it to the RadGridView columns, but I cannot.

How could I do to have RadGridView columns with the same width as the one from the RadGanttView chart columns ?

Any help or tip will be much appreciated :)
