As title.

My xaxis is DateTimeCategoricalAxis and how to use ScatterSeries?

         i would like to drag RadTreeView Node to  winform standard Panel, but when i drag and drop  to the panel , my mouse always busying

         my code as fellows 

         

          panel   is   System.Windows.Forms.Panel panel

           this.tree  is  RadTreeView

 

           this.panel.AllowDrop = true;
            this.tree.AllowDrop = true;
           

            this.tree.ItemDrag  += Tree_ItemDrag;
            this.tree.DragEnter += new DragEventHandler(this.tree_FunctionList_DragEnter);

            this.panel.DragEnter += Panel_DragEnter;
            this.panel.DragDrop  += Panel_DragDrop;

 

        private void Tree_ItemDrag(object sender, RadTreeViewEventArgs e)
        {
            RadTreeNode tn = e.Node as RadTreeNode;
            if (tn != null)
            {
                (this.tree).DoDragDrop(tn, DragDropEffects.Copy);
            }
        }

        private void tree_FunctionList_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Copy;
        }



        private void Panel_DragDrop(object sender, DragEventArgs e)
        {
            RadTreeNode node = e.Data.GetData(typeof(RadTreeNode)) as RadTreeNode;
            Console.WriteLine(node.Text);
        }

        private void Panel_DragEnter(object sender, DragEventArgs e)
        {
            e.Effect = DragDropEffects.Copy;
        }

I'm using RadControls for WinForms 2008.3 1321.

I built an application, using a RadForm as main form. If I run it on a local computer everything looks good. But if I connect a remote computer via terminal services (remote desktop / RDP protocoll) which is running a "XP based" operating system (e.g. Windows XP oder Windows Server 2003) there is an issue:

The caption bar of the RadForm won't get drawn correctly. It is invisible, most time completely, sometimes just the left part (the one with the image). But it is there, obviously: if I click on the right place of the "invisible" caption bar I'm able to drag, minimize or close the window although I don't see the system menu buttons nor the whole bar itself. If I move the window outside the visible bounds of the screen and back to screen again the caption bar gets drawn correctly, with all images, titles, buttons and so on. But if I minimize/restore the window after this the drawing problems appear again.

As I said above the issue seems to occure only on XP based remote systems. On computers running a Vista derivative (like any Vista version or Windows Server 2008) the whole window gets drawn correctly. The problem is also independent from the RDP client. It occures the same if I use a XP station or a Vista station as client, which both have different RDP client versions. The RDP connection settings (as color depht oder performance settings) are also unimportant. Furthermore, only the caption bar of the form is affected but none of its contents (and I use a lot of RadControls in it), including main menu or status bar.

Can anybody confirm similar issues - and has a solution maybe?

I am using the built-in drag and drop service.   I have 3 grids.   

 

I am implementing it so I can drag and drop Grid 2 rows onto rows of either Grid 1 or Grid 2.

 

I have no problem of dragging the Grid 2 Rows to a row in Grid 1.  All is working fine.

However if I drag rows from Grid 2 to Grid 3, I cannot get the svc_PreviewDragDrop event to trigger.  It will trigger if I drop it on the grid in general, but not if I drop it on a row in Grid 3.  

 

Cannot figure out what I am doing wrong.  

 

Thank you

 

I would like to select all rows based on the text typed in the search box or create a collection  of rows that contain the search text. 

 

For example if the user types 'cat" into the search box. is there a way to auto select those rows so the user could drag and drop.  I have the drag and drop working for selected rows, just wanted a new way  in selecting rows.   

 

For a SelectionChanged event in a hierarchical RadGridView, how do I test to determine which template had a row selection change?

Hi.

I have a problem that I could not solve somehow.

I have three CheckedDropDownLists, a button and a gridview.

My goal is to filter the data (List <SomeClass>) linked to the gridview with CheckedDropDownList elements.(I know Gridview has filtering feature and I already use it. But gridview's filtering feature hides data outside of the filter.)

I want to filter the list that I have connected to the Gridview as a data source according to the criteria I have selected with these three CheckedDropDownLists and link the newly created list to the GridView as a data source.

These are simple operations that have thousands of examples on the Internet, and I've already done so far here. 

The main problem is I can't make these three CheckedDropDownLists interactive with each other. When I make a selection on one, I want the other two updated accordingly.

If I have selected 4 company numbers from the CheckedDropDownList, which lists the company number values, the names of these four companies will appear in the CheckedDropDownList, which lists the company names. I want it to show the calculation ID values of these companies in the other CheckedDropDownList that lists the calculation Id values. It seems a little complicated, but I hope I could explain it.

I found this thread https://www.telerik.com/forums/binding-to-rangestart-and-rangeend-of-radrangeselector that RadRangeSelector's StartRange and EndRange has been changed when data object changed.

Data object can not change when I change RadRangeSelector's StartRange and EndRange by UI.

Followed as my sample code:

Hi.
I have a RadGridView that SelectionMode property is set to CellSelect.

 

After filtering by any column, when I try to get the row index of the selected cells, it gives me the index number in the rows created after the filtering process.

When I want to change the value of a cell using the obtained row index, this time it works according to the original table, not the filtered table.

So I have to get the original index number of that cell before filtering.

Hi, 

What is the method to clear or reset a layout diagram ?

I have tried the following without success ... 

        LayoutDiagram.DeselectAll()

        LayoutDiagram.Clear()

        LayoutDiagram.UndoRedoService.Clear()

        LayoutDiagram.Refresh()

Issue I am having is if there is a selected shape on the diagram, when I clear/re-add shapes, I am getting a strange side-effect where the shape's manipulation adorner becomes visible but the shape is no longer selectable. It looks like there is some "cache" behind the scenes that isn't clearing ? I would have expected LayoutDiagram.Clear is all I needed to call to reset to a "clean slate" ? Is this so ?

Kind regards,

Milan
