Xaml – Add and Update Row Definitions

Row and Column Definitions are used to set the rows and columns in a grid on a xaml page. I wanted to add or remove any of these definitions from the code behind using C#. Next is the solution:

Add Row Definitions:

RowDefinitionCollection defs = myGrid.RowDefinitions;
defs.Add(newRowDefinition(){Height=newGridLength(140)});
defs.Add(newRowDefinition(){Height=newGridLength(1,GridUnitType.Star)});

Update Row Definitions:

RowDefinitionCollection defs = myGrid.RowDefinitions;
defs[0] = newRowDefinition(){Height=newGridLength(140)};
defs[1] = newRowDefinition(){Height=newGridLength(1,GridUnitType.Star)};

To add and update columns, just change RowDefinition with ColumnDefinition in the above code. Hope this helps you in your Windows Phone and Windows Store apps! Happy Xamling!
