Hello,

I have a small amount of data that's already been grouped and sorted by sql. It looks something like this:

value - category name

25 - Cat1
15 - Cat2
5  - Cat3

Each time I run the query, I may receive different categories with different names and different values. These categories, if I understand how the ChartView works correctly, are represented via Series. Since my data is dynamic, how should I go about creating these series on the fly? Most of the examples I've seen use hard coded series. I'm sure I can hack it together, but I'd rather ask first in case there's a better way. Btw, I did search the forums and found a post where someone is using VB and Linq to get a list of categories. That may work, but its from 2012 so I thought I'd ask.

Thanks!

 Hi everybody !

   I Have this xml that load the radLayout Control?

   <RadLayoutControl TabIndex="0">
  <Items>
    <Telerik.WinControls.UI.LayoutControlSeparatorItem Bounds="0, 0, 910, 4" Name="layoutControlSeparatorItem3" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="0, 376, 455, 251" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="455, 376, 455, 251" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="0, 198, 455, 178" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="455, 198, 455, 178" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="0, 4, 455, 194" />
    <Telerik.WinControls.UI.LayoutControlItem AssociatedControlName="" DrawText="False" Text="" Bounds="455, 4, 455, 194" />
  </Items>
</RadLayoutControl>

  When load the layout from "this.radLayoutControl2.LoadLayout(pathTheXml);" My ideia is set in each LayoutControlItem the Chart. I try this:

    var itens = this.radLayoutControl2.Items.OfType<LayoutControlItem>().ToList();
            var layoutSeparator = this.radLayoutControl2.Items.OfType<LayoutControlSeparatorItem>().FirstOrDefault();

            foreach (var newTeamMemberItem in itens)
            {
                RadChartView radChartView = new RadChartView();
                radChartView.Title = "AAAAAA";
                radChartView.Name = "radChartView" + index;
                radChartView.ThemeName = this.radLayoutControl1.ThemeName;
                setChart(chartModelArea, radChartView, EnumTipoGrafico.Barra);

                newTeamMemberItem.Name = "nameStart";
                newTeamMemberItem.AssociatedControl = radChartView;
                newTeamMemberItem.DrawText = true;
                newTeamMemberItem.MaxSize = newTeamMemberItem.MaxSize;
                newTeamMemberItem.MinSize = newTeamMemberItem.MinSize;
                newTeamMemberItem.TextAlignment = System.Drawing.ContentAlignment.MiddleLeft;
                newTeamMemberItem.TextFixedSize = 26;
                newTeamMemberItem.TextImageRelation = System.Windows.Forms.TextImageRelation.ImageBeforeText;
                newTeamMemberItem.TextPosition = Telerik.WinControls.UI.LayoutItemTextPosition.Top;
                newTeamMemberItem.TextSizeMode = Telerik.WinControls.UI.LayoutItemTextSizeMode.Fixed;

                if (layoutSeparator != null)
                this.radLayoutControl2.AddItem(newTeamMemberItem, layoutSeparator, LayoutControlDropPosition.Bottom);
                else
                    this.radLayoutControl2.AddItem(newTeamMemberItem, newTeamMemberItem, LayoutControlDropPosition.Bottom);
            }

    But this doesn't work. Can you help please. Thanks
