number of characters vs. number of pixels

[Nancy Jan]

Hi,

I use the latest version of GGC. The GridColumnDescriptor.Width returns a value represents number of pixels. Instead of pixels, how to get the value in number of characters?

Thanks,

Hi Nj,

there is no precise way to convert from pixels to characters unless you do a use a fixed font and not a propertional font.

An estimate can calculated with
Graphics g;
int charWidth = (int) g.MeasureString("Abc", font).Width/3;
and then divide the column.width with charWith.

You can also determine the maximum length of characters found in the column using the

GridTable.GetColumnMaxLength(columnDescriptor)

method.

If you do not explicitly set a column.Width then the grid will actually automatically size the column by calling GridTable.GetColumnMaxLength and then multiply this with the same charWidth used above. This is done within the GridTable.GetPreferredColumnWidth(columnDescriptor) method.
