Is there a way to enable the grid for more excel-like behavior? At the very least I expect that when editing the data in a cell, the enter key ends and commits my edit.

Thanks,

Moveable/Draggable Panels

hi all,

I was hoping to get some advise if a moveable/draggable panel contianer could be acheived for radcontrols in Winforms, i am trying to create a container control that can allow the user to drag or reorder a set of panels, like in google... Any tips on how to acheive this.

I have been able to move individual panels using the mousedown and mousemove events but i guess i want to reorder/align other panels with in the same container. Any advise would be appreciated! I am using Radcontrols for Winforms Q1 2009 atm.

Binding array to radChart

Dear friends,

I want to bind some values to a radChart. I mean, for each month, i want to display in radChart the sales with success and sales without success. I use a radChar Bar, with two bars for each month where each bar represents the sales with success and without success.

How can i bind an array of 24 positions(with 24 integers inside) to my radChart and how can i change the legend of the values, replacing 'Series 1' and 'Series 2' by 'Success' and 'No Success'.

Thanks.

My code:

//this.radChart1.PlotArea.YAxis.AutoScale = false;

//this.radChart1.PlotArea.YAxis.IsZeroBased = false;

//this.radChart1.PlotArea.YAxis.AddRange(0, 100, 10);

//this.radChart1.PlotArea.XAxis.AutoScale = false;

//this.radChart1.PlotArea.XAxis.IsZeroBased = false;

//ChartAxisItem item1 = new ChartAxisItem("Jan.");

//ChartAxisItem item2 = new ChartAxisItem("Fev.");

//ChartAxisItem item3 = new ChartAxisItem("Mar.");

//ChartAxisItem item4 = new ChartAxisItem("Abr.");

//ChartAxisItem item5 = new ChartAxisItem("Mai.");

//ChartAxisItem item6 = new ChartAxisItem("Jun.");

//ChartAxisItem item7 = new ChartAxisItem("Jul.");

//ChartAxisItem item8 = new ChartAxisItem("Ago.");

//ChartAxisItem item9 = new ChartAxisItem("Set.");

//ChartAxisItem item10 = new ChartAxisItem("Out.");

//ChartAxisItem item11 = new ChartAxisItem("Nov.");

//ChartAxisItem item12 = new ChartAxisItem("Dez.");

//radChart1.PlotArea.XAxis.Items.Add(item1);

//radChart1.PlotArea.XAxis.Items.Add(item2);

//radChart1.PlotArea.XAxis.Items.Add(item3);

//radChart1.PlotArea.XAxis.Items.Add(item4);

//radChart1.PlotArea.XAxis.Items.Add(item5);

//radChart1.PlotArea.XAxis.Items.Add(item6);

//radChart1.PlotArea.XAxis.Items.Add(item7);

//radChart1.PlotArea.XAxis.Items.Add(item8);

//radChart1.PlotArea.XAxis.Items.Add(item9);

//radChart1.PlotArea.XAxis.Items.Add(item10);

//radChart1.PlotArea.XAxis.Items.Add(item11);

//radChart1.PlotArea.XAxis.Items.Add(item12);

//int[] intArray = new int[12] { 10, 11, 12, 13, 5, 5, 8, 44, 3, 5, 77, 8 };

//radChart1.DataSource = intArray;

//radChart1.DataManager.ValuesYColumns = new string[] { "numberOfOrders" };

//radChart1.PlotArea.XAxis.DataLabelsColumn

//radChart1.DataBind();

Chart (obsolete as of Q1 2013)

Trouble with Visual Studio 2010 Beta 2

Dear Sir or Madame,

having trouble with referencing any Telerik Component in the latest Version of Visual Studio 2010 Beta 2. It let me references all Controls but when i try to build the Project the References are gone. And Visual Studio tells me ... Are you missing an Assembly? --> This just happens strangly just with your Assemblys. Tryed some others. Seems like there is something wrong with Code Access Security Evidence. But i'm not quite sure.
What can i do, to get rid of this error?

Excuse me, i'm talking about: RadControls_WinForms_2009_3_1016_trial

Thx

Patric

Windows Forms not remembering Font Styling

After doing the upgrade from Q2 2009 to Q3 2009 beta all of my RadTabItems that were set to Tahoma, 12pt Bold in my RadTabStrips reset to Tahoma, 8.25pt without the bold setting. I make the change back to Tahoma, 12pt Bold, save, compile and they are fixed, but upon pulling up the form in designer mode again, all of the fonts are reset back to Tahoma, 8.25pt.

In addition, several of my RadTabStrips are defaulting to the second tab instead of the first now, is there a new property or setting to set that instead of doing a code fix?

Problem with Shortcuts and SplitContainer and/or RadDock

When I try to assign shortcuts in the shortcuts control, the userinterface disappears or I get a ”Unable to cast object of type ’Telerik.WinControls.UI.splitcontainerElement’ to ’System.ComponentModel.IComponent” error. Using shortcuts on very simple forms seems to work ok.

I am using a demo version of 2009.2.9.729 in vs2008.
