Text Color

May I know how can I change the combo box text color, example
the combobox having a list like below
Red
Blue
Green
White
Black

When that item is selected, the forecolor show on the combo box is the text color.

below are some of my code...
============================================

6:          For i As Integer = 0 To _Color.Items.Count - 1
7:              Dim item As New Telerik.WinControls.UI.RadComboBoxItem()
8:              Dim fillElement As Telerik.WinControls.Primitives.FillPrimitive = DirectCast(item.Children(0), Telerik.WinControls.Primitives.FillPrimitive)
9:              fillElement.BackColor = _Color.Item(i).CoverColor
10:             fillElement.BackColor2 = _Color.Item(i).CoverColor
11:             fillElement.BackColor3 = _Color.Item(i).CoverColor
12:             fillElement.BackColor4 = _Color.Item(i).CoverColor
                item.ForeColor = _Color.Item(i).FontColor
13:             item.Text = _Color.Item(i).Name
14:             item.Value = _Color.Item(i).Index
15:             _cboCTRL.Items.Add(item)
16:         Next

====================================
    Private Sub _ComboColor_SelectedValueChanged(ByVal sender As Object, ByVal e As EventArgs) Handles _cboCoverColor.SelectedValueChanged

1:      Dim item As RadComboBoxItem = DirectCast(_cboCoverColor.SelectedItem, RadComboBoxItem)
2:      If item Is Nothing Then
3:          Return
4:      End If

        _cboCoverColor.ForeColor = item.ForeColor
    End Sub
================================================

but seems like no luck... i only manage to change the drop down text to the color I would like it to be, but, not the text color while it's selected.

Please advice.

.NET 2.0 SP1 Required

Hi,

I am writing an application with your components and am trying to update it to 2008Q1. All has gone well (except filtering the grid but I'll figure it out).

I had to update the .NET Framework to 2.0SP1 since the following exception was being raised:

Could not load type 'System.ComponentModel.INotifyPropertyChanging' from assembly 'System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'

After the patch all is well.

My problem is that .NET2.0SP1 has a range of problems when installing. I have tested it on 5 computers and 2 have failed. I cannot release the application if the user may encounter this installation bug and may not be savvy enough to solve it.

http://msdnrss.thecoderblogs.com/2008/04/18/microsoft-net-framework-20-service-pack-1-fails-to-install/

Is there any way to get around this problem?

Thanks,

- jorge

PS. I can not require .NET 3 or 3.5 on the user machines.

VB.net samples wont build for RadControls for WinForms Q1 2008

Hello,

I downloaded the trial version of the software yet the samples for the vb.net solution will not build. It seems that the vb.net project has serious issues not having all of the forms nor references. Is there an update for this? The products seem to be extremely useful however it's a little disappointing when trying to evaluate something and the samples don't even work. Any help would be appreciated. There were over 138 errors on the build some are below:

Error 48 Unable to open module file 'C:\Program Files\Telerik\RadControls for WinForms Q1 2008\Examples\ComboBox\Binding\Form1.Designer.vb': The system cannot find the file specified. C:\Program Files\Telerik\RadControls for WinForms Q1 2008\Examples\ComboBox\Binding\Form1.Designer.vb 1 1 Examples

Error 42 'Corners' is not a member of 'Telerik.Charting.Styles.StyleChartDataTable'. C:\Program Files\Telerik\RadControls for WinForms Q1 2008\Examples\Chart\IntelligentLabels\Form1.Designer.vb 165 13 Examples

[Solved] when does RowFormatting fire

I am using the RowFormatting for alternating row color. I am also planning to use it to insert a progress bar in a column. It seems to me that the event does not fire until I click on the grid. I would like this formatting to occur when the form loads. Am I missing something?

gridview q4 beta databinding problem

This was not the problem at all. In the Beta release q1 2008, the .FieldName property was added to the grid to set the dataitem from the datasource. Not only now does it blow up if the field is not a valid field name (before it simply didn't display data), it is case sensitive. i.e. FieldName <> fieldname.
