Change to Different Sibling ChildGridViewTemplate Programmatically in RadGridView

I'm trying to implement Ctrl-Page Up / Ctrl-Page Down keys to go to the previous / next Tab (aka Sibling ChildGridViewTemplate) in a RadGridView with Tabbed Child View like what is supported in .Net's TabControl and in Tabs in Microsoft Office apps. I figure I'd have to set the GridBehavior Property to my class that overrides the ProcessKey Function. Beyond that I'm at a loss. The GridNavigator Class doesn't have a Select Next/Previous Template/View/Tab method like it does for Columns and Rows. The GridViewTemplate's IsCurrent Property is Read-Only.

Grouping on more than one field

Hello,
I'm trying to do some more complex grouping in a winforms RadGridView. What I'd like to accomplish is to do a grouping on two fields at the same level. For instance have a table of invoices and in some situations the invoice can be rejected. So what i'm trying to show is how many invoices per customer were paid or rejected for a certain date. So what I'd like to see is something like this.

to start everything Customer/Pay date level
+   CUSTOMER1    10/01/2009
+   CUSTOMER2    10/01/2009
+   CUSTOMER1    10/02/2009

then clicking on the + see:
-     CUSTOMER1    10/01/2009
    Paid            20    $200.00
    Rejected     2      $50.00
-     Customer 2     10/01/2009
    Paid            10    $100.00
    Rejected    1        $35.00

I've seen reference that something like this should be available in the Q2 2009 release and we have Q2 2009 SP1. Could someone please verify this info is correct that it is possible and if so maybe point me to an example?

Thanks

Dennis

Column settings lost in Q3/2009

Hi there

Today I installed the Q3/2009 version on my development system (side by side with the Q2/2009). After the upgrade process of the projects with the telerik utility most of the thinks looked ok. But on one user control with a radgridview on it I have the following problem:
After starting the property editor of the grid, it told me that the index is out of bounds. I don't know which index is out of bounds. After closing the message box the property editor started. But I could not see any fields of the data table. I can start "Build" in the top right corner then I see my fields. I can change the settings and press ok. The grid on the form does not show the fields and when I reopen the property editor I can see the binding source but all fields and their settings are lost.

Any ideas or workaround to fix this problem?

Kind regards
Roger

Vertical Scroll Bar Not Show Unless Adjust Parent Form Size in 2009Q3Beta

I just installed Telerik Q3 2009 WinForms BETA (2009.2.9.1016) over Q2 2009 (2009.2.9.729) and the Vertical Scroll Bar no longer shows unless adjust at run-time the Size of the Parent Form of the RadGridView. This is regardless of whether RadGridView.AutoScroll is True or not (it was working as False in Q2).

The only RadGridView change mentioned was removing separate Vertical Scroll Bars for each ChildGridViewTemplate.

Telerik 2009Q3 Beta (2009.2.9.1016), VS 2005 (v8.0.50727.762 SP.050727-7600), .Net2 (2.0.50727), XP SP3, Core2Duo 2.99GHZ with 3GB.

CurrentRow Jumping from Any-Level ChildGridView into MasterGridView when Vertical Scrolling in 2009Q3Beta

This applied to Q2 2009 (2009.2.9.729) also which was bad enough, but is a much more critical of an issue in Q3 2009 Beta (2009.2.9.1016) because users can no longer avoid it by just using the Vertical Scrol Bar of the CurrentRow's ChildGridViewTemplate due to the new combined single Vertical Scroll Bar for all Master / Child GridViewTemplates. Don't get me wrong, I love the new combined single Vertical Scroll Bar. It's a much, much better u.i. solution than separate ones. It just needs to be have its kinks worked out.

Telerik WinForms 2009Q3 Beta (2009.2.9.1016) / 2009Q2 (2009.2.9.729), VB, VS 2005 (v8.0.50727.762 SP.050727-7600), .Net 2.0 (2.0.50727), XP SP3, Core2Duo 2.99GHZ with 3GB.

Adding rows when GridView is filtered.

Dear Sir/Madam,

Is it possible to add rows when a filter is applied to the GridView?

1. I've added a filter programmatically

    
            FilterExpression filterDriver = new FilterExpression(); 
        
            filterDriver.Predicates.Add( 
        
                         FilterExpression.BinaryOperation.AND, 
        
                         GridKnownFunction.Contains, 
        
                         GridFilterCellElement.ParameterName ); 
        
            filterDriver.Parameters.Add( GridFilterCellElement.ParameterName, varFilter ); 
        
            gridAssigned.Columns[ COLUMN_DRIVER ].Filter = filterDriver;

2. While this filter is active, I want to add a new row programmatically.

    
            GridViewDataRowInfo newRow = gridAssigned.Rows.NewRow(); 
        
            [...] 
        
            gridAssigned.Rows.Add( newRow );

But this doesn't work. I also added

    
            gridAssigned.MasterGridViewTemplate.Update( GridUINotifyAction.RowsChanged );

but without success.

Thanks in advance!

Last Selected Tab?

Hi Guys,

I have a bit of an issue. When my user switches tabs I run a lengthly process, but this process only needs to be run coming from one specific tab. So... How do I identify what was the last selected tab?

Example:
----------------------------
Tab 1 Tab2 Tab3

On click of Tab2 from Tab1 I run process XYZ. On click of Tab2 from Tab3 I want to bypass process XYZ. When the user clicks on Tab2 how do I know the previous selected tab?

Many thanks,
~Mike
