Do I need to do anything other than below to refresh a gridview? (Im talking about the TableAdapter.Fill, will this cause the grid to rebind to the data automatically or do I need to include that also? (It currenly appears to be working when the timer is up it does seem to freeze up the app for a few seconds as it downloads the huge dataset but because there is so much data and it maybe 5-10min between a change its kind of hard for me to see if a change happens.

    
                Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick  
        
                    Dim Diff As TimeSpan = TargetTime.Subtract(Now)  
        
                    If Diff.Seconds = 0 And Diff.Minutes = 0 Then 
        
                        Label1.Text = "Data Refresh Now!  Stand By!" 
        
                        Me.ExpediteTableAdapter.CommandTimeout = 0  
        
                        Me.ExpediteTableAdapter.Fill(Me.MSQL_ERPLXFDataSet.Expedite)  
        
                        TargetTime = Now.AddMinutes(30)  
        
                    ElseIf Diff.Seconds < 0 And Diff.Minutes >= 0 Then 
        
                        Label1.Text = "-" & Format(Diff.Minutes, "#0") & ":" & Format(System.Math.Abs(Diff.Seconds), "00")  
        
                    Else 
        
                        Label1.Text = "Data Refresh In " & Format(Diff.Minutes, "#0") & ":" & Format(System.Math.Abs(Diff.Seconds), "00")  
        
                    End If

Hey there!

I'm working on a project what implements a treeView and a detailed ListView for file browsing. And I would like to grab the icons and file description from the system (from Windows) and add it automatically to the treeView nodes and the listview items too.

Could you tell me how is this possible in an easy way?

Hi,
" Error 1 'Telerik.WinControls.UI.RadListBox' does not contain a definition for 'SelectedIndices' and no extension method 'SelectedIndices' accepting a first argument of type 'Telerik.WinControls.UI.RadListBox' could be found (are you missing a using directive or an assembly reference?) "

Which alternative for Telerik.WinControls.UI.RadListBox.SelectedIndices in Q1 2010 ?

frm.MdiParent = this; returns null for MdiParent...

Hi folks.

I use a RadRibbonForm as my main form (MDI container) and also a RadDock control to host my MDI child forms. My main form's Load event follows:

    
                    private void MainForm_Load (object sender, EventArgs e)  
        
                    {  
        
                        if (this.IsMdiContainer != true)  
        
                            this.IsMdiContainer = true;  
        
                        string theme = ThemeResolutionService.ApplicationThemeName;  
        
                        ThemeResolutionService.ApplicationThemeName = "Office2007Silver";  
        
                        this.Text = Properties.Resources.AppName;  
        
                        this.dock.AutoDetectMdiChildren = true;  
        
                        this.dock.DocumentManager.DocumentInsertOrder = DockWindowInsertOrder.ToBack;  
        
                        this.MdiChildActivate += new EventHandler (MainForm_MdiChildActivate);  
        
                        FormPosition.LoadFromRegistry (this, Properties.Resources.AppName);  
        
                    }

The code that creates a new child form follows:

    
                        EditorForm frm = new EditorForm (file);  
        
                        frm.MdiParent = this;  
        
                        RichTextBoxEx txt = frm.Editor;  
        
                        txt.CursorPositionChanged += new System.EventHandler (CursorPositionChanged);  
        
                        txt.SelectionChanged += new System.EventHandler (SelectionChanged);  
        
                        txt.MouseDown += new MouseEventHandler (OnRichTextBox_MouseDown);  
        
                        frm.Show ();

The problem is that after the line: "frm.MdiParent = this;" (this is the main form and is not null) frm.MdiParent becomes null !!!

Can you please help me?

Thank you in advance.

[Solved] Bug when dealing with RadListBox components in the 2010Q1 VSB

I have tried to create a new style for various components in the new Visual Style Builder and got stuck when dealing with the RadListBox component. In the RadListBoxElement > RadListBoxItem sub-component both the ListBoxItemSelectionFIll and ListBoxItemSelectionBorder seem to ignore their settings, no changes are visible in the preview even if new styles are assigned to this components. The ListBoxItemText sub-component works however. If I save the resulting theme and import it in an application the same problem applies, all the settings for other sub-components work correctly (like the RadListBox border and background) but the list box items' fill and border styles seem to be ignored.

[update]

I looked deeper into the problem and realized that this is not a bug. Apparently the ListBoxItemSelectionFill and ListBoxItemSelectionBorder have by default their Visibility property set to Hidden. Changing it into Visible fixes the problem.

[Solved] Using AutoSizeColumnsMode.Fill vs BestFitColumns

Hello,

I have a few grids where I'd like to achieve the following:

Have the column widths automatically determined via grd.MasterGridViewTemplate.BestFitColumns() except when the sum of the column widths under this method is less than the width of the grid itself. In this case, set the grd.MasterGridViewTemplate.AutoSizeColumnsMode to be Fill.

I have tried to do this via the following code, but it doesn't seem to be accurate when summing the column widths, and thus I am still getting cases where the columns do not fill the grid...

                    		grdDifferences.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.None;         
                            grdDifferences.MasterGridViewTemplate.BestFitColumns();         
                            int iTotalWidth = grdDifferences.Width;         
                            int iCountWidth = 0;         
                            foreach (GridViewColumn column in grdDifferences.Columns)         
                            {         
                                iCountWidth += column.Width;         
                            }         
                            if (iCountWidth < iTotalWidth)         
                            {         
                                grdDifferences.MasterGridViewTemplate.AutoSizeColumnsMode = GridViewAutoSizeColumnsMode.Fill;         
                            }         

Any help would be appreciated.

Thanks!
