I Have a DataTable with a lot of Rows and Columns.
Some of these Rows have the Same "OrderId", actually these rows are almost the same, but I have a specific value in the "TagList" Column that I have to put in the previous row.
Making a unique Row with all the TagList values inside the TagList Column.
I'll give a example below:
Line 1:
ID: 1
Name: John
OrderId: 1500
TagList: AG75
Line2:
ID: 2
Name: John
OrderId: 1500
TagList: BG99
I wanna do it:
Line:
ID: 1
Name: Mark
OrderId: 1500
TagList: AG75, BG99
ie: Concatenate the TagList's values when they have the same OrderId.
