How do I use a theme on a RadToggleButtonElement in a RadRibbonBar?

I have some RadToggleButtonElements in a RadRibbonBar, and I'm trying to apply a theme to them. I already have a theme manager assigned to the ribbon bar, and it appears to be working correctly for the other control types on the ribbon bar. The RadToggleButton theme is loaded into the theme manager but it isn't being applied to the toggle buttons. I've checked the IsThemeApplied property on the buttons at runtime just to be sure, and it's always false. I found a previous post (http://www.telerik.com/forums/toggle-button-style) about how to add a RadStylesheetRelation to the RadToggleButton theme's xml file, and I tried that, but it's still not working. Is there something else I'm missing?

Note: This same RadToggleButton theme is used on another form as well, and it's working there, so I don't believe there's anything wrong with the theme itself. The only difference that I can see is that the toggle buttons on the other form are not being used in a ribbon bar.

Thank you!

ListView Sorting with Custom Groups and Custom Items

Hi,

I am having trouble sorting a ListView with Custom Items and Custom Groups.

I have Created a SortDescriptor and Enabled Sorting. I have also got a ListViewCustomComparer.

My ListViewCustomComparer is being called and it does appear to be comparing items fine but the ListView never appears sorted.

I did find this article http://www.telerik.com/forums/sorting-items which seems to describe my issue perfectly and it was deemed a problem in the ListView.

I am using version 2016.1.216.40 and was wondering if this was ever fixed and if so what might I still be doing wrong?

Thanks

Generate chart image without displaying the chart

I'm using RadChart v2011.3.11.1219 with a .Net 4.0 WinForms app using VS 2010 sp1. In this app I am displaying a couple of charts, but I am wondering if it is possible to generate a line chart and save it to png without ever displaying the chart?

How would I go about doing that?

Export to Pdf images not rendered

I have tried searching everywhere and I have found no mention of the issue I am running into. Using a winforms application I add a png image to a radgridview. Then I export the Radgridview to a pdf file. However, in the pdf the image only shows up as the text "System.Drawing.Bitmap". Any idea what could cause the image to not render for the pdf? It looks just fine within the radgridview. I'm currently using version 2010.2.10.914 of the winform controls. Any help would be greatly appreciated.

This is the code I used to produce the Pdf.

private void AddImage(RadGridView TheGrid, MemoryStream mStream)

{

Image TheImage = System.Drawing.Image.FromStream(mStream);

GridViewImageColumn ImageColumn = new GridViewImageColumn();

ImageColumn.ImageLayout = ImageLayout.Stretch;

ImageColumn.Width = 1095;

ImageColumn.IsVisible = true;

radGridView1.MasterGridViewTemplate.Columns.Add(ImageColumn);

radGridView1.MasterGridViewTemplate.Rows.Add(TheImage);

radGridView1.Refresh();

}

radGridView1.MasterGridViewTemplate.Columns.Add(Chart);

radGridView1.MasterGridViewTemplate.Rows.Add(ChartImage.Image);

radGridView1.Refresh();

}

private void radGridView1_Click(object sender, EventArgs e)

{

if (this.radGridView1.Rows.Count != 0)

{

ExportToPDF exporter = new ExportToPDF(this.radGridView1);

exporter.FileExtension = "pdf";

exporter.ExportVisualSettings = true;

exporter.PageTitle = "Chart";

exporter.FitToPageWidth = true;

exporter.PdfExportSettings.EnableCopy = true;

exporter.SummariesExportOption = SummariesOption.ExportAll;

string fileName = "C:\\ExportedData.pdf";

exporter.RunExport(fileName);

}

[Solved] Values Being Rounded

I might just be missing a very simple property here... the rows appear fine as soon as the application is run, but as soon as you click on a row, the value is rounded to two decimal places. Here's my code:

private void RadForm1_Load(object sender, EventArgs e)

{

RadPropertyStore PropertyStore = new RadPropertyStore();

radPropertyGrid1.SelectedObject = PropertyStore;

PropertyStore.Add(new PropertyStoreItem(typeof(double), "test", 184.9484));

PropertyStore.Add(new PropertyStoreItem(typeof(double), "test2", 341651.7823));

}

I tried to force the decimal places to remain the same using this, but it did not work:

private void radPropertyGrid1_EditorInitialized(object sender, PropertyGridItemEditorInitializedEventArgs e)

{

PropertyGridTableElement te = sender as PropertyGridTableElement;

PropertyGridSpinEditor editor = e.Editor as PropertyGridSpinEditor;

if (editor != null && te != null)

{

((BaseSpinEditorElement)editor.EditorElement).DecimalPlaces = 5;

}

How can I prevent my values from being rounded?

Thanks!

[Solved] Printing Grid with Logo in RadPrintDocument Footer

I'm having issues using the [Logo] feature when attempting to print a grid. For my test, I've got a png file at a size of 63x18 pixels and I want to place it in the LeftFooter. It does print it, but the logo is stretched instead of retaining its shape. I've attached an image of what I'm seeing.

Here is a snippet of code I'm using in my testing.

var doc = new RadPrintDocument();

doc.HeaderHeight = 20;

doc.FooterHeight = 18;

doc.HeaderFont = new Font("Arial", 10, FontStyle.Bold);

doc.FooterFont = new Font("Arial", 8, FontStyle.Regular);

doc.LeftHeader = "Test Header";

doc.Logo = System.Drawing.Image.FromFile(@"Z:\Home\Kurt\Y&M Logos\ymlogo_63x18.png");

doc.LeftFooter = "[Logo]";

doc.Landscape = true;

doc.AssociatedObject = radGridView1;

doc.Print();

If I had the ability to set the Width of the LeftFooter, or force the size of the Logo, I'd be set, but I can't find a way to do this. Any ideas?
