Change focus on node select

Hello,

I want to select a control in my form when the user selects a node.
This works when selecting the node with the keyboard but when i select a node with the mouse, the node gets the focus after the SelectedNodeChanged event.
Is there any way to tell the Treeview not to steal the focus?

Row border - visibility and colors

I want to display the bottom border of by rows in white so that I get a nice single line between rows.

I have played with code like:

Private Sub RadGridView1_RowFormatting(sender As Object, e As Telerik.WinControls.UI.RowFormattingEventArgs) Handles RadGridView1.RowFormatting

e.RowElement.DrawBorder = True
e.RowElement.BorderColor = Color.White
e.RowElement.BorderTopWidth = 0
e.RowElement.BorderBottomWidth = 2
e.RowElement.BorderLeftWidth = 0
e.RowElement.BorderRightWidth = 0

and

Private Sub RadGridView1_CellFormatting(sender As Object, e As Telerik.WinControls.UI.CellFormattingEventArgs) Handles RadGridView1.CellFormatting

e.CellElement.DrawBorder = True
e.CellElement.BorderColor = Color.White
e.CellElement.BorderTopWidth = 0
e.CellElement.BorderBottomWidth = 4 ' Setting to 1 or 2 didn't show
e.CellElement.BorderLeftWidth = 0
e.CellElement.BorderRightWidth = 0

but either I cannot get anything to display until I set the bottom width to 4 pixels, or I get lots of other border items shown as well.

Any ideas please?

Limit the GridviewDecimalColumn text length or maxlength inside a gridview cell

Hello,
I am using a radgridview in which I am adding a gridviewdecimalcolumn, but I want to restrict the user from entering the specific number of decimals.
Eg: If I am having a column and I enter the value for it '123456789' then it gets entered while if i want to restrict the user to enter the value only upto 3 places i.e 123 it isn't possible as in if I am giving the maximum then it changes to 999 but I don't want it like that I want that if the user enters the value as '333' then it should get entered only upto that number of decimal places after that if the user enters any number it should not get displayed or entered.So how to do this?

There is a amazing program which has been developed by you. "Use custom filtering to search in all columns of RadMultiColumnComboBox".
http://www.telerik.com/support/kb/details/use-custom-filtering-to-search-in-radmulticolumncombobox
It is very good, handy and really wow.
But when you hit enter key on MultiColumnComboBox for 3 times, you get an NullReferenceException exception.
Can you fix it?

Thanks

RadGridView scrolls up when hover out and when TelerikMetroTouch theme is selected

Hello everyone

It sounds very strange but it's the very truth. I have a RadGridView in my WinForm application. For this RadGridView I'm using "TelerikMetroTouch" theme. When I scroll down to the bottom and then hover out of the GridView, it just scrolls up to the middle of the RadGridView.
First I thought it must have something to do with my code so I commented everything and then started the application again. But the behaviour stays the same. I was very confused and couldn't find any help on the internet.
Then I created a test application and copied the GridView into it. It has the same behaviour. The last thing I tried to do was changing the theme. I couldn't believe it when I saw that that strange bevaviour disappears when changing the theme to "VisualStudio2012Light".

So the summary is: When I'm using "TelerikMetroTouch" theme for Telerik RadGridView control, it scrolls up to the middle when I first scrolled down to the bottom and then hovering out. But when I'm using "VisualStudio2012Light" theme, it doesn't scroll.

Does anyone saw that behaviour before or can anyone provide some help?

Regards,
Danilo

[Solved] Prevent Multiple Tabs

Hello!
I have a radform with a button, when I click it, a usercontrol form opens in a tab inside the radpageview, all nice, but if I click the same button, the same usercontrol open in another tab.. so, the question is, how I can prevent this? for example instead of open the same tab, maybe it can focus to the tab that is already open with the usercontrol in it,

this is the basic code for my button:

1.RadPageViewPage page = new RadPageViewPage();

2.UserControl1 uc = new UserControl1();

3.

4.page.Text = "Page Test ";

5.radPageView1.Pages.Add(page);

6.page.Controls.Add(uc);

7.radPageView1.SelectedPage = page;

what type of if statement do I need here?

Thanks!
btw, amazing job with this .net toolbox! Thanks!

Programaticly Adding Data to Multicolum Combox Box

Please can we have an example of adding a row to the Multi Column Combo Box, that does not use a Datasource

I wanted to have a column with a name and another with a checkbox.

it seems rather simple, but there is no example in the documentation that details a simple add items

I did manage to add records via a datatable, but this does not add to the existing columns in the control, but adds new columns
And does not set the value of the checkbox

Sub LoadData()

Dim table1 As DataTable = New DataTable()

table1.Columns.Add("ID")

table1.Columns.Add("Name")

table1.Columns.Add("Selected")

table1.Rows.Add(1, "Ivan Petrov", True)

table1.Rows.Add(2, "Stefan Muler", True)

table1.Rows.Add(3, "Alexandro Ricco", False)

cboTestCheckbox.DataSource = table1

cboTestCheckbox.DisplayMember = "Name"

End Sub
