Question

I’ve a DataGridView that looks like so:

                  DGV 
       | Col 1 | Col 2 | Col 3 |

I was wondering if it is possible to remove the first column when I’m writing to a datatable so that it’ll look something like this:

             DataTable
        | Col 2 | Col 3 |

Additionally, is it possible to eliminate rows that contain a certain value? So if the value is in the datagridview, I want to remove it from my datatable.
E.g.

                  DGV 
       | Col 1 | Col 2 | Col 3 |
       | Value | One   | Two   |
       | Value | Three | Two   |
       | Value | Four  | Two   |

So if there’s the value “Three” in the DataGridView, the DataTable would be

             DataTable
        | Col 2 | Col 3 |
        | One   | Two   |
        | Four  | Two   |

Any help would be much appreciated! I’ve already tried parsing row by row, but I’m wondering if there’s a more efficient way to achieve this.

Simply, you can do like this to meet your above condition:

var dtableDemo = new DataTable();
dtableDemo = this.dgvDemo.DataSource as DataTable; //// Getting the datatable of datagridview datasource
if (dtableDemo != null)
{
    dtableDemo.Columns.RemoveAt(0); //// Removing the first column of derived table

    dtableDemo.Rows.Cast<DataRow>().Where(
               row => row.ItemArray.Contains("put_your_value_to_check")).ToList()
               .ForEach(row => row.Delete()); //// Remove the row if it contains the given value
    dtableDemo.AcceptChanges(); //// Finalize the delete
}
