Hi
Kindly make sure that you remove the after getting concatenated and we can use remove datacolumn activity as well

Hi…

Nope. It didn’t work with Remove DataColumn either. You can verify with the Xaml that was attached.

Hi

Any solution for this ? I need to remove the datacolumns after I have the concatenated column.

Col1 Col2 Col3 where Col3 is the concatenation of Col1 and Col2.

After its done I need to remove Col1 and Col2.

Could you please help ?

We can get with DefaultView method like this

dt = dt.DefaultView.ToTable(False,”Col-3”)

This will give only the col-3 in that datatable

Thanks for your swift reponse.

But I need something like removing the data columns as I have a lot of columns that are to be kept and the columns that are to be removed are comparatively less

Can you help ?
