Hi.

How to save TreeView. I have no problem read data from database, like this:

   Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load

        Me.TblSkydeHoldTableAdapter.Fill(Me.SkyttecenteretDataSet.tblSkydeHold)

        Me.RadTreeView1.DisplayMember = "name"
        Me.RadTreeView1.ParentMember = "pid"
        Me.RadTreeView1.ChildMember = "id"
        Me.RadTreeView1.ValueMember = "id"

        Me.RadTreeView1.DataSource = Me.GetSampleData()

    End Sub

    Private Function GetSampleData() As DataTable

        Dim dt As New DataTable()
        Dim dc As New DataColumn()
        dc.ColumnName = "id"
        dc.DataType = GetType(Integer)
        dt.Columns.Add(dc)
        Dim dc1 As New DataColumn()
        dc1.ColumnName = "name"
        dc1.DataType = GetType(String)
        dt.Columns.Add(dc1)
        Dim dc2 As New DataColumn()
        dc2.ColumnName = "pid"
        dc2.DataType = GetType(Integer)
        dt.Columns.Add(dc2)


        Me.TblSkydeHoldTableAdapter.Fill(Me.SkyttecenteretDataSet.tblSkydeHold)

        For Each dRow As DataRow In Me.TblSkydeHoldTableAdapter.GetData
            Dim dr As DataRow = dt.NewRow()
            dr(0) = dRow.Item("dr0")
            dr(1) = dRow.Item("dr1")
            dr(2) = dRow.Item("dr2")
            dt.Rows.Add(dr)
        Next

        Return dt

    End Function

But my problem starts when i want to save back to database. When i add a new node, the node have no parentmember value or valuemeber value. Is it possible to add those values automaticly when a new node is created?

Kindly Peter

I am creating ScatterSeries

                    var scatterSeria = new ScatterSeries
                    {
                        XValueMember = "COLUMN0", YValueMember = "COLUMN1", 
                        HorizontalAxis = horizontalAxis1, 
                        VerticalAxis = verticalAxis1,
                        Shape = new CircleShape(),
                        BackColor = Color.Red,
                        BorderColor = Color.Black,
                        PointSize = new SizeF(10.0f, 10.0f),
                        IsVisibleInLegend = true
                    };
But the border of the shape is not drawn in black on the chart. But the same shape is drawn in the legend with a black border.

In a legend, I draw a shape using

        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;
        }

How to set the border color for the shape on the chart?

Hi, I've got  a TabControl, with several TabPages, with RadGridViews i nthem.

I pretty much let the GUI do most of the wiring up of the grids & data..

Everything seems to be working except, I'm getting the above message when I

Add a new Row.

As soon as the row is added, I get the icon on the row, and that message.

The row adds just fine, and I can update it, & delete it as well.

Without posting the entirety of the projects code, is there a place I might look to first, to find why I've

apparently got two datareaders open?

Attached is what I see after adding that new row, and scrolling to the bottom of the data grid.

Hello,

I use radrangeselector to quick scroll and zoom-in my radchartview.

At first, I show a part of my chart by using radrangeselector. The export as image works great. Only the part that I zoomed is exported.

But when I print by calling "RadChartView1.printpreview()", the image which I got is shifted.

Please find the photos in attach files.

You can download my demo in this link:

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?
