RadGridView with GridViewColumnGroup printing left to right columns

[elad]

Hi,

I have a RadGridView control which bind by ColumnGroupsViewDefinition with GridViewColumnGroup.

The grid direction is from right to left.

When I use the PrintPreview methods, the grid in the preview become from left to right.

 

How can I fix it?

Thank you.

Hello,

Can you please confirm whether use the PrintPreview approach demonstrated on this example? If so, does the FlowDirection flips for the whole control, or for the ColumnGroups only?

Hi,

Thank for your reply.

I don't use silverlight...I use Telerik for winforms.

The method I use is:

RadPrintDocument printDoc = new RadPrintDocument();
printDoc.Landscape = isLandscape;
printDoc.RightHeader = header;
printDoc.HeaderHeight = 100;

printDoc.AssociatedObject = this;

RadPrintPreviewDialog dialog = new RadPrintPreviewDialog(printDoc);
dialog.Size = new System.Drawing.Size(Screen.PrimaryScreen.Bounds.Width - 200, Screen.PrimaryScreen.Bounds.Height - 200);
dialog.SetZoom(0.80);
dialog.ShowDialog();

 

Thank,

Elad

Hello Elad,

Thank you for writing.  

I have logged it in our feedback portal and I have added a vote for it on your behalf. You can track its progress, subscribe for status changes and add your comments on the following link - feedback item.

I have also updated your Telerik points.

Currently, the possible solution that I can suggest is to use the following code snippet:

public class CustomGridPrintStyle : GridPrintStyle
{
    protected override BaseGridPrintRenderer InitializePrintRenderer(RadGridView grid)
    {
        if (this.PrintRenderer != null)
        {
            this.PrintRenderer.PrintCellPaint -= renderer_PrintCellPaint;
            this.PrintRenderer.PrintCellFormatting -= renderer_PrintCellFormatting;
            this.PrintRenderer.ChildViewPrinting -= renderer_ChildViewPrinting;
        }

        BaseGridPrintRenderer renderer = null;

        if (grid.ViewDefinition.GetType() == typeof(ColumnGroupsViewDefinition))
        {
            if (!(renderer is ColumnGroupsViewDefinitionPrintRenderer))
            {
                renderer = new CustomColumnGroupsViewDefinitionPrintRenderer(grid);
            }
        }
        else if (grid.ViewDefinition.GetType() == typeof(HtmlViewDefinition))
        {
            if (!(renderer is HtmlViewDefinitionPrintRenderer))
            {
                renderer = new HtmlViewDefinitionPrintRenderer(grid);
            }
        }
        else
        {
            if (!(renderer is TableViewDefinitionPrintRenderer))
            {
                renderer = new TableViewDefinitionPrintRenderer(grid);
            }
        }

        renderer.ChildViewPrinting += renderer_ChildViewPrinting;
        renderer.PrintCellFormatting += renderer_PrintCellFormatting;
        renderer.PrintCellPaint += renderer_PrintCellPaint;

        return renderer;
    }

    private void renderer_PrintCellPaint(object sender, PrintCellPaintEventArgs e)
    {
        this.OnPrintCellPaint(sender, e);
    }

    private void renderer_PrintCellFormatting(object sender, PrintCellFormattingEventArgs e)

Thank you for your reply.

I try to use this code but I have no ChildViewPrinting event and no GetCorrectedColumnBounds method in my Telerik.WinControls.UI  reference.

I use Telerik.WinControls.UI version 2013.1.220.40. r=RunTimeVersion v4.0.30319.

How can I use it?

Hello Elad, 

Thank you for writing back. 

The provided workaround is applicable for the latest official version R3 2016 SP. I would recommend you to upgrade in order to benefit from all the introduced improvements in the 4 years versions gap. 

I hope this information helps. If you have any additional questions, please let me know.
