Adding dynamically columns and fill its in rows

[Guillaume]

Hello,

In my project, i have a GridView which has fixed columns and, according to, collection of my objects, i have to add dynamically columns.
I can add dynamic columns but I can't access to each row and fill in the values ​​of each new column.

Each fixed column is binded to a property of my objects but dynamical columns are not binded because their properties doesn't exist in my objects.

So, how can i get each row of GridView ?

Regards,
Guillaume

Hello Guillaume,

Generally, it is always recommended to work with the underlaying data item and set the values of the corresponding properties. Consequently, I would definitely suggest you to expose appropriate properties for the columns you want to add. If not and a value is set for a particular cell, it will be most probably lost during scrolling due to the grid's virtualization.

Hello Guillaume,

Yet another possible solution would be to benefit from the DataTable for Silverlight as illustrated in this blog post.
