Exporting to PDF, column width issue.

[Mike]

Hi,

I have an issue exporting a gridview to pdf when the gridview has a horizontal scrollbar and is wider than the container.

If I export without scrolling, the columns on the right hand side do not have their actual widths set properly, and are much less wide than the other columns. However, if I first scroll the scroll bar, and then scroll it back, when I export, the columns are the correct width.

Is there a way to programmatically do this? Is there a call on the gridview to auto size or best fit the columns or something like that? Do the columns actually have to be displayed on screen for the export to have the actual widths set?

Hello Mike,

I guess the problematic columns are sized "Auto" . For such columns RadGridView relies on the Measure and Arrange layout passes to determine the width of the column .

In order to get more accurate results you may need to turn off the column virtualization .

Turn off column virtualization does the trick. Thank you.

hello Pavel,

I know this is quite old, but i just can't seem to make it work with my current code. Is there something i am missing here?

private void ExportToPdfClick(object obj)
{
    var file = System.IO.Path.Combine(Path.GetTempPath(), ExportDefaultSaveName + "_" + DateTime.Now.ToString("yyyyMMddHHmmss") + ".pdf");
    EnableColumnVirtualization = false;
    using (Stream stream = File.Create(file))
    {
        this.ExportToPdf(stream,
            new GridViewDocumentExportOptions()
            {
                ShowColumnFooters = true,
                ShowColumnHeaders = true,
                ShowGroupFooters = true
            });
    }
    EnableColumnVirtualization = true;
    Process.Start(file);
}

 

Thank you!

I have found a workaround by adding this line

new GridViewDocumentExportOptions()
                    {
                        AutoFitColumnsWidth = true,
