FileFilters
(string) The file type filters that will be used in the browse. Defaults to "All Files (*.*)|*.*|". These filters control which file types will be visible in the file browse dialog. For example, if you want to filter only executables, you could have "Executables (*.exe)|*.exe|". "Executables (*.exe)" is the description that will appear in the "Files of type" field on the dialog and can be any text you want. "|*.exe|" represents the file filter that will be used internally.
You can also include multiple filters that can be selected. For example, "Executables (*.exe)|*.exe|Text Files (*.txt)|*.txt|". The second filter will be available on the dialog from the drop down in the "Files of type" field.
You also have the ability to specify more than one pattern for a filter by separating the patterns with semicolons. For example, "Pictures (.png, .jpg, .tif)|*.png;*.jpg;*.tif|".
