Hello,
the UltraGridPrintDocument should print WYSIWYG by default, that's what I thought. But printing a Grid, where all the columns are displayed correctly on screen, takes away 1 character from the values in almost every column when printed (or in the PrintPreview). Now, the values are shortened and an ellipsis is shown.
That's all I coded:ultraGridPrintDocument.Grid = this.gridReport;ultraGridPrintDocument .Print();
Is there an easy way to get WYSIWYG, instead of working around in InitializePrint or InitializePrintPreview with column.PerformAutoResize?
Thanks for your help!
The grid DOES print WYSIWYG. The problem is that the screen uses different drawing units than the printer. So the width of the column on-screen may fit the text perfectly, but when the same width is used on a printer, the text may not fit the same.
Calling PerformAutoResize on each column on the print layout accounts for this, since the print layout knows to use printer metrics and not screen metrics.
It is not working.
My Grid is in split container. i have only 3 columns.
Grid.AutofityStyle = ExtandedLastColumn.
I did steps accordint as you said. But didnt work. Following is the code
{
}
e.DefaultLogicalPageLayoutInfo.FitWidthToPages = 1;
...Just to confirm I'm doing the sizing in the form load to make things look nice when first loaded.I'm redoing the resizing on print preview like covered in this topic.
NB: There are a few thousand rows of data, as well as the 50 columns.
2 minutes seems excessive. How many rows does your grid have?
Keep in mind that autosizing a column is an expensive operation for a couple of reasons.
First, in order to resize the column, the grid has to load every row into memory. Depending on your data source and the number of rows, this can be an expensive operation. It's espeically expensive if you are using a DataSet with relationships. The DataSet is not very efficient when getting child rows.
You might be wondering why child rows matter if you are only autosizing the parent band. They matter because, by default, the parent and child columns have their widths synchronized, so they autosize together.
Fortunately, the rows only need to be loaded once, so the number of columns doesn't really matter.
The second thing is text measurement. The grid has to measure the text in every cell of the entire grid. This means that each cell object has to be created and it's appearance has to be resolved (to determine the font being used). So if you have 50 columns with 100 rows, that's 5000 cells, 5000 appearance resolutions, and 5000 text measurement operations.
This is one of the reason that the default autosizing in the grid only uses the visible rows instead of AllRowsInBand. Maybe for effiiciency, you should only autosize based on the first few rows. You can specify a number of rows to PerformAutoSize.

The problem is still the print preview can't have any "..."I suppose if they're mental enough to print preview thousands of rows, then they'll have to wait!
How do I measure the strings in the printer context?
This is in InitializePrint/InitializePrintPreview.Do I somehow need the Graphics object.On the screen I'm doing the following:Graphics gr = reportGrid.CreateGraphics();...SizeF size = Infragistics.Win.DrawUtility.MeasureString(gr, summaryValue.SummaryText, font);
You would have to use a graphics object from the printer. But I don't think there's any way to get that until the PrintPage event fires, which is probably too late.
If you call PerformAutoResize on a column that is in the print layout, it will handle this for you and measure correctly for the printer, though.
