Dynamic Grid.ColumnDefinitions in windows phone 8

Question

I need a row with three equal sized columns,

So I declared like,

<Grid.ColumnDefinitions>
    <ColumnDefinition Width="*"></ColumnDefinition>
    <ColumnDefinition Width="*"></ColumnDefinition>
    <ColumnDefinition Width="*"></ColumnDefinition>
</Grid.ColumnDefinitions>

Now, sometimes, any one of my column may be hidden, in that case the remaining two should get equal width. How to achieve this?

Answer 1

You can easily change particular ColumnDefinition 's Width to 0 for hiding corresponding Grid 's column and getting the remaining columns equal width, for example :

//get column definition for the 1st column
var col = myGrid.ColumnDefinitions[0];
//set it's width to 0
col.Width = new GridLength(0);
