[Solved] 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.

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.

[Solved] 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!

[Solved] 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

Automatically sort with drag and drop.

Dear,

I implemented some drag&drop functionality with two GridViews.
Now when I drag one row to the other GridView, it should automatically sort the GridView based on a default column.

I've added a sort expression programmatically at the beginning of my program:

    
            gridAssigned.MasterGridViewTemplate.SortExpressions.Add( "Order" );

Inserting a row (drag&drop):

    
            object[] values = new object[ 10 ]; 
        
            [...] 
        
            gridAssigned.Rows.Add( values );

Is there some extra code needed in an event when adding this row? Because now it's added at the bottom of the GridView.
Thanks in advance!

Not Scrolling if Moving CurrentRow in ChildGridViewTemplate off Visible Area in 2009Q3Beta

This only applies to Q3 2009 Beta (2009.2.9.1016) vs. Q2 due to the new combined Vertical Scroll Bar for all Parent / Child GridViewTemplates. If you move a CurrentRow that's inside a ChildGridViewTemplate up / down via keyboard out of the Visible area of the RadGridView, the RadGridView does not scroll until the CurrentRow reemerges into one of the MasterGridViewTemplate Rows.

ChildGridViewTemplates' Heights Too Short on 2009Q3Beta

I just installed Telerik Q3 2009 WinForms BETA (2009.2.9.1016) over Q2 2009 (2009.2.9.729) and due to the single Vertical Scroll Bar for all Parent / Child GridViewTemplates, Child GridViewTemplates now always expand to a height that can show all its Rows (or rather is supposed to). For me it's just short enough so that the last 1 or 2 Rows dol not show and of course the SummaryRows, if any, aren't showing either. I know the Rows are loaded and there's nothing wrong with the SummaryRows because if I Group the Rows by one or more Columns, they're there (probably because the Child GridViewTemplates no longer require as much height when their Rows are Grouped). All the Rows and SummaryRows used to show in Q2 2009 albeit possibly requiring manual adjustment of the GridViewTemplate height or scrolling it down to see them both of which or no longer applicable in Q3 2009. I have EnableGrouping and EnableFiltering set to True and am using default Header / Data Row Heights.
