Hi WK,
Thank you for using Syncfusion products.
We have developed a sample as per your requirement. In our sample we have used the MappingName of the column name and then we will be changing the Column Header text. This would help you in solving your issue.
Please refer the code snippet and sample from the following:
[Code Snippet]
this.dataGrid.ItemsSource = new Task2();
var CT = (from vc in this.dataGrid.VisibleColumns where vc.MappingName == "Language" select vc).First();
var a = new TaskDetails();
CT.HeaderText = a[1].Language.ToString();
