Hi…

I’ve got vb.net form connected to MS database (.mdb)…
I set data type some columns of DGV to int32 with certain formats…
For instance:
Col 1 value:00000078
Col2 value:011
Col3 value:0005

I would like “col 4” to be set as a primary key:
Col 4 value (PK) will result: 000000780110005

So what the codes to generate primary key based on values joined from multi-columns cells for data grid view?!

Hope My Q is clear !

Best Regards…
