In my last windows project I was supposed to create a Layout Management tool where user can create web layouts through a windows application.
This tool is having following functionality.
1- Create multiple rows.
2- Create multiple columns.
3- Merge Cell.
4- Split Cells
Requirements were similar to the table control present in the MS Office, where user can resize rows.
I implemented this using WPF Grid control and the resizing part is done through GridSplitter control. While implementing this tool the main issue I faced was to persist the layout, so that it can be loaded exactly same every time (mainly height/width of rows and columns and the exact location of the GridSplitter).
For persisting I thought of standard serialization technique, but it’s not possible to serialize a WPF framework element using binary or Xml serialization technique.
So finally I decided to store the XAML of the grid to the database and use the XAML to load the layout back.
I have used following code to generate the
code from the grid.
private XmlDocument GetXAMLFromGrid()
StringBuilder outstr = new StringBuilder();
XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.OmitXmlDeclaration = true;
XamlDesignerSerializationManager dsm = new XamlDesignerSerializationManager(XmlWriter.Create(outstr, settings));
dsm.XamlWriterMode = XamlWriterMode.Expression;
XmlDocument doc = new XmlDocument();
For restoring the Grid from the
I used following code.
private Grid GetGidFromXAML(string xamlText)
Grid grid = (Grid)XamlReader.Parse(xamlText);
