Even though I can change using Inherited form, I was wondring if there is a way to completely disable it and replace it with my own form that would update the SQL tables directly (along with other things in the database). My question is about disabling the edit dialog and relacing it with my own... If you happend to provide examples, would you please provide VB.net?

Thanks

Tab key not switching between columns

Good morning,

I am creating gridviews programmatically but the TAB key is not functioning within the gridviews. When I click the tab key it either does nothing or, if the controls is in edit mode, it just highlights the entire value within the control. How do I get the TAB key to jump between cells?

    
            RadGridView gridView = new RadGridView();  
        
            gridView.Name = name;  
        
            gridView.Anchor = (System.Windows.Forms.AnchorStyles)(System.Windows.Forms.AnchorStyles.Top | System.Windows.Forms.AnchorStyles.Left | System.Windows.Forms.AnchorStyles.Right);  
        
            gridView.AutoSize = true;  
        
            gridView.AutoScroll = true;  
        
            gridView.MasterGridViewTemplate.BestFitColumns();  
        
            //gridView.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;  
        
            gridView.MasterGridViewTemplate.AutoGenerateColumns = false;  
        
            gridView.MasterGridViewTemplate.AllowAddNewRow = true;  
        
            gridView.ShowGroupPanel = false;  
        
            gridView.ContextMenuOpening += new ContextMenuOpeningEventHandler(gridView_ContextMenuOpening);  
        
            gridView.GridBehavior = new MyBehavior(); // see behavior below  
        
            gridView.CellBeginEdit += new GridViewCellCancelEventHandler(gridView_CellBeginEdit);  
        
            gridView.CellValueChanged += new GridViewCellEventHandler(gridView_CellValueChanged);  
        
            gridView.StandardTab = true;

I've tried the "StandardTab" property set to true and false, neither of them work.

Thank you,
Scott Vercuski

BestFit problem on Q3 2009

Hi,

We have a problem with the rendering of the grid(version 2009.3.9.1203) since we upgrade to version 2009 Q3.

He is the code we use to set the columns width :

Me.Instance.DataSource = Value

Me.Instance.GridElement.BeginUpdate()

If Me.Instance.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None Then

For Each column As GridViewDataColumn In Me.Instance.Columns

column.BestFit()

End If
Me.Instance.GridElement.EndUpdate()

Since we update, the column.BestFit() don't work and all column have like width of 1...? We usually have grid with more than 10 columns and it has always work fine.

What should we do to fix it?

thx

Adjusting scroll speed?

Hello.

Default behaviour for a radgridview is to scroll one whole "page" when using the mousewheel to scroll, however I would like to change this to something like 5 rows at a time. Is this possible?

Best Regards, Joel

Treeview with big checkboxes

Hi all,

I was wondering if there's a way to resize the treeview checkboxes - I am changing an application to be used with a touchscreen, and the current checkbox is too small to click using your finger. Anyone has any advice?

Thanks.

Filtering boolean column

Hi,

I fill the grid like this:

bindingSource.DataSource = typeof(MyClass); //MyClass has a property of boolean type which are represented by checkboxes in the grid as well as string properties

grid.EnableFiltering = true;
grid.MasterGridViewTemplate.EnableFiltering = true;

grid.DataSource = bindingSource;

//refresh the binding source

As you can see, I enable filtering programatically. The problem is that no filtering for bool columns is available. I can filter text columns by manually entering some text in the filter row (however no menu/editor/designer is shown for this, I can only enter text and the LIKE operator is applied automatically), but there is no way to filter checkbox columns.

What can be the cause of such strange behavior, how can I solve this problem?

Thanks,

Maciej Aniserowicz

ExportToExcelML : Could not find neighbour element!

Hello,

I just have installed the new Q3 2009 package and I still have an error when I try to export my radgriView into an Excel file.

Before upgrading I had an index out of range error.

After upgrading I have : Could not find neighbour element!

I'am using this very simple piece of code :

                    Dim documentTop As AnalyseForm = CType(MainDock.DocumentManager.ActiveDocument.Controls(0), AnalyseForm)         
            Dim exporter As New ExportToExcelML(documentTop.DataGrid)         
            exporter.SheetMaxRows = ExcelMaxRows._65536         
            exporter.ExportVisualSettings = True         
            Dim fileName As String = "c:\ExportedData.xls"         
            exporter.RunExport(fileName)         

Thanks for your help
