[Solved] AutoSize columns in Fill mode with a fill weight

Is there a way to achieve the following:
I want to have a grid with AutoSizeColumnsMode set to Fill, but I want for example one column twice the width of the others.
E.g. I have 2 column. The first should take 1/3 of the space, the second 2/3.

Issues with Pan/Zoom, Tool Tips, Smart Labels, etc.

HI all,

I'm really not sure what I'm doing wrong here. I can't get any of the above working in my project.

If I set ShowPanZoom = true; I still can't pan or zoom (I've tried directly adding the controller)

If I try to add tool tips, that fails too.. Here's my code:

rcvMain.Controllers.Add(new ChartTooltipController());

Smart Labels also gives the same thing.

Is there something else I need to enable to get any/all of these working?

Thanks!

Rob.

ExportToExcelML Creating bad files?

Seems that since I've upgraded the ExportToExcelML command has been failing on me. It creates a file no problem, but I'm getting an "Excel cannot open the file 'blah.xlsx' because the file format or file extension is not valid." error.

Here is what I'm doing (and this worked prior to the recent upgrade)

void btnExportExcel_Click(object sender, EventArgs e)

{

this.SaveFileDialog.Filter = "Excel Workbook (*.xlsx) |*.xlsx|Excel 97-2003 Workbook (*.xls)|*.xls";

if (this.SaveFileDialog.ShowDialog() == DialogResult.OK)

{

ExportToExcelML exporter = new ExportToExcelML(this.dgResults);

exporter.HiddenColumnOption = Telerik.WinControls.UI.Export.HiddenOption.DoNotExport;

exporter.ExportVisualSettings = true;

exporter.SheetName = this.GridTitle;

if (Path.GetExtension(this.SaveFileDialog.FileName) == ".xls")

{

exporter.FileExtension = "xls";

exporter.SheetMaxRows = ExcelMaxRows._65536;

}

else

{

exporter.FileExtension = "xlsx";

exporter.SheetMaxRows = ExcelMaxRows._1048576;

}

try

{

this.lblReady.Text = "Exporting to Excel...";

this.StatusStrip.Refresh();

using (new UtilLib.Winforms.WaitCursor())

{

exporter.RunExport(this.SaveFileDialog.FileName);

}

catch (Exception ex) { UtilLib.Winforms.Feedback.DisplayError(ex); }

finally

{

this.lblReady.Text = "Ready";

}

Anyone else experiencing the same issue?

RadWaitingBar in RadStatusStrip issues...

Hello...

I am attempting to get a RadWaitingBar to work in a RadStatusStrip and having some issues... my status strip is build like this...

RadWaitingBar (200px) | RadLabelElement (Spring) | RadLabelElement (200px)

I found the article of putting the RadWaitingBar in a RadHostItem at...

http://www.telerik.com/community/forums/winforms/statusstrip/radwaitingbar-in-radstatusstrip.aspx

and followed the instructions but still the center LabelElement is over-springing all the way to the left underneath the RadHost + RadWaitingBar...

I am building this entirely in code due to the RadHostItem...

    
            private RadWaitingBar waitingBar = new RadWaitingBar(); 
        
            private RadLabelElement _statusLabelElementCenter= new RadLabelElement(); 
        
            private RadLabelElement _statusLabelElementRight= new RadLabelElement(); 
        
            waitingBar.BeginInit();  
        
            waitingBar.Size = new Size(200, 16);  
        
            waitingBar.MinimumSize = new Size(200, 16);   
        
            waitingBar.MaximumSize = new Size(200, 16); 
        
            waitingBar.EndInit(); 
        
            statusLabelElementCenter.AutoSize = true; 
        
            statusLabelElementCenter.Margin = new System.Windows.Forms.Padding(1); 
        
            statusLabelElementCenter.Text = "Here is some really long text that shows how the controls are overlapped."; 
        
            statusLabelElementRight.AutoSize = false; 
        
            statusLabelElementRight.Size = new Size(200, 16); 
        
            statusLabelElementRight.Margin = new System.Windows.Forms.Padding(1); 
        
            statusLabelElementRight.Text = "Right Label"; 
        
            //WaitingBar in RadHostItem, RadHostItem in PanelElement, based 
        
            //upon suggestions in previous post. 
        
            RadStatusBarPanelElement stripPanel = new RadStatusBarPanelElement(); 
        
            stripPanel.Size = new Size(200, 16); 
        
            stripPanel.Padding = new Padding(0); 
        
            stripPanel.Children.Add(new RadHostItem(waitingBar)); 
        
            radStatusStrip1.BeginInit(); 
        
            radStatusStrip1.Items.Add(stripPanel); 
        
            radStatusStrip1.Items.Add(statusLabelElementCenter); 
        
            radStatusStrip1.Items.Add(statusLabelElementRight); 
        
            radStatusStrip1.SetSpring(statusLabelElementCenter, true); 
        
            radStatusStrip1.EndInit();

when I run this... I get the following (attached image).... as you can see, the RadWaitingBar is on top of the center LabelElement.

Any ideas on how to fix this?

suppres row/cell receycling (Virtual mode)

Hello supportteam,

according to the article "Create pop-up user control for row editing" we implemented a UserControl acting as a roweditor, which is hosted in a RadMenuHostItem by a Custom cell - all works fine. As proposed in the example the editor control is instantiated in a RadGridView.CreateCell event handler.

Now the problem: When I remove a row from the grid and add a new one the CreatedCell handler will not be called, I guess because there is no need hence the grid receycles the removed row to display the new one (Virtual mode).

Is there a way to suppres "receyling" of gridrows, so CreatedCell is fired all the time I call RadGridView.Rows.AddRow? Performance is not a not problem as the the number of rows will be just a few.

Best regards &
Thanks for any advice,
Oliver

ListView DragDrop (and other questions)

I'm having trouble implementing DragDrop to sequence the ListViewDataItems. I've seen the forum entry from 2011 about enabling DragDrop and I voted for that feature. I see the DragDrop event in ListView but it doesn't seem to fire. Is this feature coming soon or am I failing to implement it correctly?

The attached picture should help clarify this. I also want to:
2. Hide borders on ListViews.
3. Use some type of panel (FlowLayoutPanel or Rad anything) where I can prevent a horizontal scrollbar from appearing but show the vertical scrollbar.
4. Put some kind of label above the ListView that implements the current theme (backcolor, backcolor2, backcolor3, backcolor4) like RadButton or the text area on the ToolWindow.
5. Control the location of text (and Images) on the ListViewDataItem so I can move it (them) to the right some x pixels.

Thank you,
Gary

RichRibbonBar Error on Save

Using the RichRibbonBar, I get an error any time I use the "Save" button. I don't get the error when using "Save As". This happens when using the QuickAccessToolbar or the File menu.

The error is "Object reference not set to an instance of an object." in this Sub on the line "Me.SaveDocument(button.Tag.ToString())"

Private Sub buttonSave_Click(ByVal sender As Object, ByVal e As EventArgs)

Dim button As RadButton = TryCast(sender, RadButton)

Me.BackstageControl.HidePopup()

Me.SaveDocument(button.Tag.ToString())

End Sub

Details View: Column Header Appearance

I put a ListView with ViewMode.DetailsView next to a GridView. I made one of the two columns not visible. I'd like the visible column's column header to have the same appearance (color) as the column headers in that GridView. How do I do that?

Thank you,
Gary
