I am trying to setup the charts so that only the plot area is shown and the chart has no border. I can't seem to find the correct border property. There is a border property on the chart object itself that is set to false. Is the chart border coming from the skin?

Thank you.

Best data binding strategy?

I’m developing a c# win app using RadGrid. I would preferably like to be able to use the grid property builder in design time to configure columns, dropdowns etc. On the other hand I would like to work with business objects (using EntitySpaces or similar) to access the data in SQL Server and later implement remoting or similar technologies to migrate to a true n-tier client server app. Anyone having some suggestion regarding an architecture that makes it quick and easy to build the app using RadGrids, but enough ‘future safe’ and object oriented to work in a business application?

Could Microsoft entity framework and Linq to Objects be the solution?

Regards,

Erik

ScreenTipNeeded Event Handler

Hello,

I've got a couple questions. The first is related to a ScreenTipNeeded Event Handler that I've programmatically added to all of my controls. Essentially, I'm wondering how I can determine what control has invoked the handler using the sender or eventargs variables. In my attempt below, the o variable is null...

                            void AllControls_ScreenTipNeeded(object sender, ScreenTipNeededEventArgs e)         
                    {         
                        RadOffice2007ScreenTipElement screenTip = new RadOffice2007ScreenTipElement();         
                        Control o = sender as Control;         
                        string sHelp = "This is help text for " + o.Name;         
                        screenTip.CaptionLabel.Text = string.Empty;         
                        screenTip.MainTextLabel.Text = sHelp;         
                        e.Item.ScreenTip = screenTip;         
                    }         

Second, as you may have guessed, the purpose of this is to provide help text for each of my controls on the screen. I've come up with this method of using the screentips, but I was wondering if there was a better or more standardized way for achieving this sort of thing?

Thanks!

Cancel cell editing

Hello,
I have a grid with certain fields that are not editable depending on the value of other fields on that row. The best way I came up with to handle this was to wire up the CellBeginEdit event, and if the field is not allowed to be edited, then cancel the event.

    
             Private Sub rgvLines_CellBeginEdit(ByVal sender As Object, ByVal e As Telerik.WinControls.UI.GridViewCellCancelEventArgs) Handles rgvLines.CellBeginEdit  
        
                    Select Case e.ColumnIndex  
        
                        Case rgvLines.Columns("MFG_ENTITY_ID").Index  
        
                            Dim lineCategoryTypeId As Integer 
        
                            Dim lineCategoryShortName As String = Nothing 
        
                            'Get the Line Category short name  
        
                             lineCategoryTypeId = CType(rgvLines.CurrentRow.Cells("LINE_CATEGORY_TYPE_ID").Value, Integer)  
        
                             lineCategoryShortName = GlobalMethods.GetTypeDefShortNameForTypeID(lineCategoryTypeId)  
        
                              If lineCategoryShortName = AppDefs.LineCategoryShortName.Group  
        
                                   e.Cancel = True 
        
                              End if   
        
                      End Select 
        
                End Sub

This all works fine but the problem that I am having is that if the user has tabbed into this cell, then focus still stays with the cell that editing was cancelled for. The default behavior is for tabbing to skip over read-only columns. So once I cancel the CellBeginEdit event, how can I get to the next editable cell? Is it possible to simulate the tab key press programmatically?

Thanks,
Sean

Problem whit adding New row whit code.

Hello

I`m Using 2 DataGrid (Master/Detail) and wanna add new row in both of them, so i`m wrote on button Click event this code.

    
            // Adding Row On Master  
        
            GridHdr.Rows.AddNew(GridHdr.Rows.NewRow());  
        
            // If new row is first row current row being null then i`m changing it.  
        
            if (GridHdr.CurrentRow == null)  
        
               GridHdr.CurrentRow = GridHdr.Rows[0];  
        
            // Filling Hdr Primerykey  
        
            GridHdr.CurrentRow.Cells["pkID"].Value = HdrID;  
        
            GridItm.Rows.AddNew(GridItm.Rows.NewRow());  
        
            // On DetailGrid current row, if is first row thats not null  
        
            if (GridItm.Row.Count == 1)  
        
               GridItm.CurrentRow = GridItm.Rows[0];  
        
            // Filling Itm PrimeryKey  
        
            GridItm.CurrentRow.Cells["pkID"].Value = ItmID;  
        
            // Filling Itm FKey  
        
            GridItm.CurrentRow.Cells["fkHdrID"].Value = HdrID;

but when button Click event was end, GridItm.Rows.Cells["pkID"].Value and other Cells has not value.
and when GridItm lost focus Itm new row lost, because has not fkHdrID (it`s Relation) Value.

Regards.
