How to dynamically add a new column to an SfDataGrid that gets it's values from a dictionary

I want to display a table of data. Each row is an instance of my class "Fruit", each column is a date.

Sort of like this:


I can store the data however is needed, but both the number of columns and rows is variable.

My hope is that the simplest solution is that I store the data as a Dictionary<DateTime, int> (or perhaps as Dictionary<string, int>) as a child property of Fruit, and set a MappingName along the lines of "FruitDict[01/01/2016]" when adding a new column to display that particular date.

Hi Daniel,

Yes. You can achieve your requirement using Dictionary type is one of the underlying collection property and display the value in column as mentioned your update.  We have prepared the sample based on this and you can download the sample from the below location,

Code Example: Add Column from XAML

<Syncfusion:GridTextColumn MappingName="dictionary[03/01/2016]" HeaderText="03/01/2016"    />

Code Behind:

private void Button_Click(object sender, RoutedEventArgs e)


            this.datagrid.Columns.Add(new GridTextColumn() { MappingName = "dictionary[04/01/2016]", HeaderText = "05/01/2016" });
