Hi

I have 2 treeviews.

When i highlight one item on treeview 1 and drag and drop to tree view 2. While the mouse button is kept pressed, and i hover on treeview 2, i would want the hovered node to be highlighted or style changed.

In the example in the attachment, the node "jacket" is to be highlighted..when the node "car" is dragged over it.

May I know if this can be done?

Hi Team,
       On the cell end edit mode the enter key event is working fine and it is firing the keydown event from the CellEditorInitialized and gets updated with the given value on the other grid. - This is the actual process.

Is it possible to have the same functionality while pressing the tab key?

I created custom shape

    public class LineShape : ElementShape
    {
        public override GraphicsPath CreatePath(Rectangle bounds)
        {
            var path = new GraphicsPath();
            path.AddLine(bounds.X, bounds.Y + 1.0f, bounds.X + bounds.Width, bounds.Y + bounds.Height);
            return path;
        }
    }

When I add a ScatterSeries, then assigned Shape = LineShape. But these points are not drawn on the chart!!!

However, if I add an event

        private void LegendElement_VisualItemCreating(object sender, LegendItemElementCreatingEventArgs e)
        {
            e.ItemElement = new LegendItemElement(e.LegendItem);
            if (!(e.LegendItem.Element is ScatterSeries seria)) return;
            e.ItemElement.MarkerElement.Shape = seria.Shape;
        }

then LineShape drawn in the legend

HI,

I have set the data source in my grid view. When I add the next data source, I want the new data source add, not the existing data source to be cleared.

Hello folks.  I've been dealing with this for several years now and cannot crack this nut so hopefully I can properly explain the issue.

1) Create a new Telerik VB Windows Forms Application

2) Click OK to select Telerik VB Windows Forms Application

3) Select 'Word-Inspired' from the "Create New Project Wizard"

4) Open MainForm in the Designer

5) Add VisualStudio2012LightTheme

6) Select MainForm in the Designer and change the ThemeName property to "VisualStudio2012Light"

7) Click 'Apply current form's theme to controls'

Everything looks good so far!

Run the Ap...there's a quick compile and our simple one form ap launches and looks great!!!

Upper-Left-Normal.png shows the upper left corner.  It's perfect.  I opened this small image in photoshop so I could put a contrasting color around the button group so you can see where it is more clearly.  This is shown in Upper-Left-Normal-Enhanced.png

Same for Upper-Right except the Control Box has the same background as the menu bar so instead I highlighted the Close button.  These are Upper-Right-Normal.png and Upper-Right-Normal-Enhanged.png

Now...this is where the Magic Happens...MAXIMIZE the form.

You can clearly see the top several pixels of the form are getting chopped off - and what makes things even more untidy are if you are running on two monitors when this form is MAX size the "sliver of missing pixels" on the right are actually there...but they are on the 2nd monitor having bled over!  Max should never cross monitors...it should fill just the active monitor minus any space taken up by Window's status bar.

You can see this in the screen shots:

 

I have not tried this with all of the themes but I have tried with several and every one I've tried does this.

Any thoughts, suggestions, help would be VERY helpful!!

 

Kindest regards...stay home!

-Curtis

Hi, I have a RadGridView where I want to add a custom filter operator to the alternatives that is already existing.

If a "-" is between two strings (like "03-15"), would like it to look something like this:

           

 

I have all the filter logic, but I can't figure how to add a new filter operator. Is it possible? Then, how to do it?

If it is not possible, then I would want to make a custom filtering row that has only the custom filtering method, how should I then create a filter row that has only the filter functionality that I want?

If I could use the filter row as I wanted without the existing filter logic, then I could use the text in the filter text box to make a custom filter, or try to build a composite filter with many BeginsWith that covers the desired range.

So what I need is a custom filter operator (would be the best in my mind), or a way to customize the filter row to do only the operation I need.

Regards,
Joar

Hello!

I need to capture when column-resizing with a mouse has COMPLETED.  I expected this would be done in ColumnWidthChanged but for reasons unknown to me that event fires WHILE the user is resizing...exactly like how I would expect ColumnWidthChanging  to work.

 

It's like the resize is happening "Live" instead of waiting for the user to complete their resize THEN firing. 

Any suggestions would be very much appreciated!

I have several forms with RadLayoutControl that looks fine in the Designer, but then running the application, they go completely wild.

I recently enabled HDPI support, all my usercontrols without LayoutControl work fine, but LayoutControl seems to be different.

Pic1 is from Designer, Pic2 from the running application, and I created a minimal reproducable example but I'm unable to attach it here.

Yes, I put Visual Studio in the 96dpi Mode, before using the Designer.

I tested on several computers, but everywhere the same awkward result.
