[Solved] Dynamic Columns

[Peter]

Hi I'm trying to populate the Columns in a RadDataGrid, and am having trouble here.

I have a Dictionary<string, IList<object>>, where the string represents a column name, and the IList<object> is the items under that column.  I don't know what the column names are going to be until runtime.  Is there a way I can implement this?

Currently the AutoGenerateColumns assumes each property in an object is a column.  This makes it difficult to dynamically create columns at runtime.

Any help would be much appreciated!

Thanks

Hello Peter,

Thank you for the question.

I suggest that you change the data structure that holds the items. The RadDataGrid needs a collection of ExpandoObject items. The ExpandoObject class implements the IDictionary<string, object> interface and for every item you will need to add a key-value pair with the name of the column and the corresponding cell value. I have attached a sample project that demonstrates how to do this.

I hope this helps. Please, let us know if you have further questions.
