AcceptChanges causes unwanted GridView behavior

I have an application with 3 GridViews bound to 3 datatables. I use a single VB subroutine with the GridView as an argument to write changes in these datatables to an Oracle database. In this subroutine, after the database has been updated, I call RadGridView.DataSource.AcceptChanges to reset all the data row states. My problem is this:

In a GridView with, let's say 500 rows, I select row 250 and position it in the middle of the displayed rows. After the save routine completes and RadGridView.DataSource.AcceptChanges is called, the GridView refreshes and the selected row is now displayed at the top of the GridView. This behavior disrupts the users' workflow. Is there any way I can suppress this refresh?

Thanks,
Robert S.

Select Template in hierarchical gridview

Hello Guys

As you can see the attached file, I have a gridview with 4 hierarchical views, I need that when the user click one of the tabs of the hierarchical view, and other row is expanded the selected tab view will be the previous selected. And if more of 1 row is expanded and the user change the hierarchical view, in all the expanded rows change the selected tab view to the selected for the user.

I tried to make it with the RadGridView1_ChildViewExpanding Event but i didnt find the Select Tab Property,
in the hirarchical view

Private Sub RadGridView1_ChildViewExpanding(ByVal sender As System.Object, ByVal e As Telerik.WinControls.UI.ChildViewExpandingEventArgs) Handles RadGridView1.ChildViewExpanding

'RadGridView1.Templates.GetTemplateByCaption(e.ParentRow.ActiveView.ViewTemplate.Caption)

Dim stemplate As String

If e.IsExpanded = False Then

For Each row As GridViewRowInfo In RadGridView1.Rows

If (row.IsExpanded = True) Then

stemplate = DirectCast(row, Telerik.WinControls.UI.GridViewHierarchyRowInfo).ActiveView.ViewTemplate.Caption

Exit For

End If

Next

End If

End Sub

Saving Mask Column Text instead of Value

I am using a GridViewMaskBoxColumn for formatted string entry, because I am working with an existing data store that contains text entries. I would like to save the fully formatted value, not just the entered characters .

Am I able to bind the column so that the Text property of the cell editor is saved to the data store instead of the Value property. It would be the difference between storing :
masked Value : 1234567890
masked Text : 12-34-567-89-W0

Here is the columns Designer code.

gridViewMaskBoxColumn1.FieldName = "LSD";

gridViewMaskBoxColumn1.HeaderText = "ll-ss-ttt-rr-mm";

gridViewMaskBoxColumn1.Mask = "00\\-00\\-000\\-00\\-\\W0";

gridViewMaskBoxColumn1.MaskType = Telerik.WinControls.UI.MaskType.Standard;

gridViewMaskBoxColumn1.Name = "LSDM";

gridViewMaskBoxColumn1.Width = 120;

RadSelectedNodesCollection missing in latest TelerikWinform control???

Good morning everyone,

I have a project that uses Telerik WinForm controlls and the version is 2010.2.10.0914 and it works perfectly. It compiles and runs. I recently upgraded to the latest telerik winform controls 2011.2.11.0831 and i am getting compile errors where the project is trying to look for the RadSelectedNodesCollection class. It doesn't seem to be available in the dlls i am using in the project.

The dlls i'm using are:

Telerik.WinControls
Telerik.WinControls.GridView
Telerik.WinControls.UI
TelerikCommon

I was looking in the documentation as well and this class is not in there either.

Has this class been renamed in the latest telerik winform controls???

thank you very much for all your help

Is it possible to outline fonts?

I have a light blue button in my application and would like to add text to the button in a different, but also light, color. As it stands now it's totally unreadable. If there was a way to add a black outline around the font that would make it pop out and be easily readable, but I have no idea if this is possible. I see that I can add a border around the label itself, but what I want is a border around each letter. Is this possible?

GridView Integer Column - Rounding

I have a GridViewDecimalColumn that I'm using to store integers entered by the user. I set the DataType property equal to GetType(Integer) (I'm using VB.NET). When a user enters a value such as 24.8, it automatically gets rounded up to 25. If they enter 24.2, obviously it gets rounded down to 24. The users shouldn't be entering decimal numbers, but I've heard that they have been and they don't ever want the numbers to round up.

My question is this: How can I force the value to always round down, so that 24.8 will be changed to 24? I know I can use a cell value change event, but I was hoping there was some property in the GridViewDecimalColumn that could be set to handle this.

Thanks,
Robert S.

ComboBox with 'entities'

Just getting started with Telerik controls...

I need to get the behavior of the RadDropDownList for a column in a GridView.

For the RadDropDownList, I am using databinding to link the SelectedValue to the property of a Business Object or Entity.

I'm trying the same approach in the GridView but no luck.

I have added a GridViewComboBox column and set its DataSource to the list of entities I want in the drop down list. That works fine, and when displaying data the correct item is highlighted. However, trying to pick a new item from the list gives this error: "Object of type 'System.String' cannot be converted to 'mynamespace.Product'.

I can see in the docs it wants me to set the ValueMember to the property on the data source that I want to use, but I don't want to use a property, I want the whole object. How can I do this??

I found this other post and the poster was in the same situation as I am:
http://www.telerik.com/community/forums/winforms/gridview/csla-bindinglist-with-default-objects.aspx

It is from 2010 - so has anything changed or is it still not supported? Do I still have to make up some kind of workaround?
