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);

}

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!

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?

Winform - AutoCompleteBox - single select

Hello,

I want to make use of the AutoCompleteBox so the user has a nice autocomplete feature, without him being able to input other values then the ones in the autocomplete items. I've been looking for this some time now, but it seems like in WPF and Web it's the SelectionMode property. But in my Winform project, there is no such a property.

Can you tell me if this is possible and if so, how (which winform property i need to set). I'm using latest .net, latest telerik updates etc. Control is RadAutoCompleteBox.

Thanks a lot!

best regards,

Francois

PivotGrid cell disappear after Export to Excel

Hi there,

There seems to be a bug with the PivotGrid when using the Export to Excel function.

Using the Demo Application for WinForms, you can just open the PivotGrid - Export to Excel example and then export one.

After that, minimize the Demo Application to task bar, and maximize it back. Some of the rows will be missing. If you keep minimizing and maximing, the rows that are disappearing will keep changing.

I'm not sure if this bug is just on my machine or if there's anything that that needs to be installed.

Thanks!
