Questions on UI for WinForms Forum

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!

Keydown event on the RadribbonForm

Hi,

I use a RadribbonForm as a mybase.
When I push one button Radribbonform changed to maximize dialog, and it will be topmost and have no button.

For returning normal dialog, I want to use keydown event(Escape key). However it dosen't work.

Can I get any sample source or example key event on the radribbonform?

Thanks,

I am using the 2008 Q2 version in Winforms.

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

            if (GridHdr.CurrentRow == null)  
        
               GridHdr.CurrentRow = GridHdr.Rows[0];

Paint issue when hide/show tool windows

When hiding or showing a tool window, there is a noticeable flicker on the rest of the controls in the rad dock. Setting the AutoHideAnimateMode to None seems to help a little but I can still see the flicker.

Setup:
I have two docking windows with user controls pre-loaded. I have four tool windows with user controls dynamically loaded.

Observations:
If I remove the pre-loaded user controls from the docking windows, there is no flicker. If I dynamically load the user controls into the docking window, the flicker occurs.

Thoughts?

Paint issue when serealizing from XML

When loading the RadDock from a previously saved XML file, there is a noticeable paint issue. The first thing drawn on screen is one of the docked windows, then about a second or two after that, the rest of the dock loads. Simply turning off the loading from XML fixes the issue. I thought it might be a problem with the RadDock's active window being incorrectly set, but after reading this post (http://www.telerik.com/community/forums/winforms/dock/autohide-doesn-t-seem-to-work-for-right-docked-toolwindows.aspx) and explicitly setting the active window, I don't think active window is the issue because the paint problem persists.

Thoughts?
