Cannot Add multiple chunks programmatically

Hello everyone,

Not sure if this has been discussed before, But I am using a code mentioned in the Help to add multiple chunks.

Dim RadRibbonBarChunk1 As RadRibbonBarChunk = New RadRibbonBarChunk()
Dim RadRibbonBarChunk2 As RadRibbonBarChunk = New RadRibbonBarChunk()
Dim RadRibbonBarChunk3 As RadRibbonBarChunk = New RadRibbonBarChunk()
RadRibbonBarChunk1.Text = "Options"
RadRibbonBarChunk2.Text = "Text"
RadRibbonBarChunk3.Text = "Alignment"
Dim RadRibbonBarCommandTab1 As RadRibbonBarCommandTab = radRibbonBar1.CommandTabs(0)
RadRibbonBarCommandTab1.Items.AddRange(New Telerik.WinControls.RadElement() { _
RadRibbonBarChunk1, RadRibbonBarChunk2, RadRibbonBarChunk3})

Unfortunately it gives me an Error in the above statement,
System.InvalidCastException was unhandled
Message="Unable to cast object of type 'Telerik.WinControls.RadElement[]' to type 'Telerik.WinControls.RadItem[]'."

Can someone help me to add multiple chunks or tell me what am I doing wrong here...

TreeView Clear() function

Ok,

I'm having a problem that is driving me crazy.

I have a RadTreeView that is updated each time someone changes rows in a DataGridView that is besides the RadTreeView. Now the thing is that on some ocations, there are no entries to be displayed on the RadTreeView. I use clear each time a row change occurs, but the RadTreeView still keeps the values of the old entries, even after calling the RadTreeView.Clear() function and then RadTreeView.Refres().

Now, shouldn't this clear the RadTreeView and leave it with NO nodes?

Thanks,

Ricardo

Selecting nodes programatically

Hi,

I want to be able to set the "Selected" property of a node, before I add it to the RadTreeView.

The following code will NOT select the node:

RadTreeNode node1 = new RadTreeNode("node1");
node1.Selected = true;
this.radTreeView1.Nodes.Add(node1);

but if I set the "Selected" property *afterwards*, it will work

RadTreeNode node1 = new RadTreeNode("node1");
this.radTreeView1.Nodes.Add(node1);
node1.Selected = true;

Is this a bug or by design. If by design can you explain the reasoning behind this?

Regards,
Phi Le

RadPanelBar constant Flickering

I am trying to create radPanelBarGroupElement dynamically and add it to aRadPanelBar. Before I add the group element to the panel bar, I am adding a custom control to the element. I am using a button to trigger the creation of additional group elements with a custom controls on them. The problem is that a tremendous amount of flickering occurs when I try to accomplish this task. What should I be doing to prevent this flickering from happening? Or what am I doing wrong? And what should I do to fix it?

Thanks.

LabelsColumn Chart

Hi,

I'm using a radChart (pie) for a small datasource. The dataset looks like this:

gebruiker     totaal
Kevin             11
Joeri              14
Ken               34

Now I want to see the pie, with a legend wich color is for wich name. I think this something easy to do, but I'm now trying for 3hours already and still cannot find it :(

If it can helps, this is how I make my Test DataSet:

            GrafiekData grafiekLijst = new GrafiekData();  

            GrafiekData.GrafiekDataRow newGrafiekRow;  

            newGrafiekRow = grafiekLijst._GrafiekData.NewGrafiekDataRow();  

            newGrafiekRow.gebruiker = "Kevin";  

            newGrafiekRow.totaal = 789;  

            grafiekLijst._GrafiekData.Rows.Add(newGrafiekRow);  

            GrafiekData.GrafiekDataRow newGrafiekRow2;  

            newGrafiekRow2 = grafiekLijst._GrafiekData.NewGrafiekDataRow();  

            newGrafiekRow2.gebruiker = "Ann";  

            newGrafiekRow2.totaal = 129;  

            grafiekLijst._GrafiekData.Rows.Add(newGrafiekRow2);
