Hi,

I must be missing something obvious but how do I set the background colour of a Gridview control.
I can set the background colour of a row or cell but I cannot see how to set the colour of "White space" in other words my grid takes up have the screen but it might only contain 2 rows, which I can colour, but the bank space is always white.

Any ideas how I can change this??

Cheers

Shaun.

TrackballTextNeeded event not firing (all the time)

I have configured the ChartTrackballController and added it to the ChartView. The event does fire, but there are times when it does not. I can move the mouse pointer left and right over the chart and most of the time the text is updated and displayed. However, there are times when the mouse is moved the data point is moved but the trackball information is not moved or updated. The event never fires.

Is this a known issue?

// Configure the trackball.
var trackball = new ChartTrackballController();
pingChart.Controllers.Add(trackball);
pingChart.ShowTrackBall = true;
trackball.TextNeeded += TrackballTextNeeded;

        private void TrackballTextNeeded(object sender, TextNeededEventArgs e)
        {
            Debug.WriteLine("{0} - trackball calculation.", DateTime.Now);

            e.Text = "Test...";
        }

RadBrowseEditor and Application Settings

Using 2013.1.220.40 version of RadBrowseEditor, I don't seem to be able to get the ApplicationSettings binding to work properly. My only choice is to bind the "Text" property, but the property that contains the path is "Value". Am I doing something wrong?

For now I've used this as a workaround:
On FormLoad or any time the settings are refreshed

RadBrowseEditor1.Value = My.Settings.PMSFolder

And when the user clicks the Save button

My.Settings.PMSFolder = RadBrowseEditor1.Value

My.Settings.Save()

[Solved] Properties Grid will not show error messages / formatting with the Visual Studio 2012 Light Theme

I am having trouble getting error messages / error formatting to show up when using the Visual Studio 2012 Light theme

The code below will show an error message on the property grid with the Control Default theme but not with the Visual Studio 2012 Light Theme.

public partial class Form1 : Form

{

MyObject myObject = new MyObject();

public Form1()

{

InitializeComponent();

radPropertyGrid1.SelectedObject = myObject;

}

private void radPropertyGrid1_PropertyValidating(object sender, Telerik.WinControls.UI.PropertyValidatingEventArgs e)

{

if (e.Item.Name == "Count")

{

if (int.Parse(e.NewValue.ToString()) > 5)

{

(e.Item as PropertyGridItem).ErrorMessage = "Count Must Be Less Than Four";

e.Cancel = true;

}

public class MyObject

{

public string Name { get; set; }

public int Count { get; set; }

public DateTime When { get; set; }

public MyObject()

{

When = DateTime.Now;

}

Indicating focus for controls

Using Telerik version 2013.1.220.40

We would like to indicate when controls (TextBox, Dropdownlist, Checkbox etc) has focus, many users use the tab-key and can't see where the cursor is. Is the best way to accieve this by creating a custom theme or just override OnFocus/LostFocus-event for all the controls and set style there?

In the application we let users choose between 5 different themes.
