Questions on UI for WinForms Forum

Hi,

I am currently using Rad Control for Winforms Q2 and Q3 2013.

I am developing a winform application and trying to use MetroTheme.

MetroTheme has a feel of light green in almost everywhere such as top border of winform border.

I'd like to change this color scheme slightly and create my own style theme. All the style elements should stay the same as MetroTheme except that this light green color should be replaced with my own color like light gray.

I tried to use Visual Style Builder and watched some video tutorials but couldn't find the solution.

Can you help me please?

Thanks,

Patrick

RadStatusStrip's RadLabelElement & Backgroundworker Question.

I was under the assumption that any UI element you wanted to update from the Backgroundworker had to be in the ProgessChanged event. However, I have noticed, only by accident, that I have been able to update the RadLabelElement's Text property w/ in the BackGroundWorker DoWork event. Is this by design? I have not been able to find any documentation on this related to the RadLabelElement.

TIA

Excel like filtering - hide filtering symbol in column header

Hello,

is it possible to hide the filter symbol in a specific column header while excel-like filtering remains enabled?

I have to filter a specific column via some radio buttons only.

This works for me:

Private Sub rbAktiv_CheckedChanged(sender As Object, e As EventArgs) Handles rbAktivAuftraege.CheckedChanged

Dim filter As New FilterDescriptor()

Dim filtervalue As String = String.Empty

filter.PropertyName = "oa_status"

filter.[Operator] = FilterOperator.Contains

filter.IsFilterEditor = True

Select Case True

Case sender Is rbAktivAuftraege

Me.RGV_auftraege.FilterDescriptors.Clear()

filtervalue = CStr("aktiv")

filter.Value = filtervalue

Me.RGV_auftraege.FilterDescriptors.Add(filter)

End Select

Best Regards,

V. Adler

Macros and Dropdown

Hi,

I use a spreadsheet to display a xlsm file which contains buttons and data validation from a list.

The attached file "Excel" shows how this file looks in Excel.

The attached file "SpreadSheet" shows how this file looks in the spreadsheet :

- the data validation in the cell works correctly according to the list but drop down arrow is not shown in the cell even if the options "In-cell dropdown" is checked

Thanks for your help

Can't set SelectValue in databound dropdownlist

What I'm trying is so simple, but doesn't work

-----------------------------

Imports Telerik.WinControls.UI

Public Class frmListTest
Private dtTest As DataTable

Private Sub frmListTest_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
fillDataTable(dtTest) ' procedure fills the table from an Oracle database procedure

myDropDownList.DataSource = dtTest

myDropDownList.ValueMember = "VALUE_MEMBER"
myDropDownList.DisplayMember = "DISPLAY_MEMBER"

End Sub

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
myDropDownList.SelectedValue = 6 ' DOES NOT WORK
End Sub

-------------------------------------

dtTemp structure
value_member display_member
24 Athletic Operations Building
1 Camp Randall Stadium
34 Camp Randall Stadium Misc.
22 Cr Sports Center [shell] - Womens Hockey
37 Goodman Diamond All Season Practice
6 Goodman Softball Complex
23 Kellner Hall
2 Kohl Center
35 La Bahn Arena
4 McClain Center

The dropdown list loads ok, but I can't select an item through the SelectedValue property.

What am I doing wrong, or not doing?

Saving Modifications...

Hi Dear Telerik :)

Maybe this is a dumb question....

In the First Look example when you use a button... is there any way to save this modifications and stored as xml or database field or something and then load this later to affect the behavior of the button maybe in the onLoad event of the main form ?

Also, it's possible to use the PropertyGrid with objects of a parent form? I mean, clicking a button and property grid loaded in a child form affecting properties of some control of the parent form?

And with that ... is there a way to assign controls programmatically to the propertygrid?

Thanx in advance!

:)
