How to get distinct values of a Data Grid?
Hi,
I would like to get the distinct column from a Data Grid. Example, data grid has the following records:
ID | Name | Country
--------------------------
1 | John | US
2 | Fred | Canada
3 | Ben | US
Would like to get the distinct country (US and Canada) and display it on another DataGrid or to Data Table.
Thanks

The TableView component has a method ToTable which will do this.

Hi ,
You can use the following code to get the distinct values. Hope this helps.
var distinctIds = dt.AsEnumerable()
.Select(s=> new {
id = s.Field<string>("YourColumnName"),
})
.Distinct().ToList();
foreach(object o in distinctIds)
{
Type t = o.GetType();
PropertyInfo[] pi = t.GetProperties();
foreach (PropertyInfo p in pi)
{
//Here you will get distinct value for your given column.
MessageBox.Show(p.GetValue(o).ToString());
}
}
