the parameterized query was not supplied default vs method

Question

I'm using visual studio to make a front end database for my work. However I am currently receiving the error

" The parameterized query '(@IsNull_Company int,@Original_Company sql_variant,@IsNull_Conta' expects the parameter '@IsNull_Company', which was not supplied."

When I try to delete something off the server. I'm assuming that this is the piece of code responsible which is just the default method VS made up for me.

 this._adapter.DeleteCommand = new global::System.Data.SqlClient.SqlCommand();

Judging from the error message I have no clue what @IsNull_Conta is I think it cut off part of @IsNull_Contact but I don't know why.

Edit: The actual method where the error is taking place is

private void employer_ContactsBindingNavigatorSaveItem_Click(object sender, EventArgs e)
        {
            DialogResult dialogResult = MessageBox.Show("Are you sure you want to make these changes? (any records deleted or changed " +
                "can not be reverted)", "Confirm Change", MessageBoxButtons.YesNo);
            if (dialogResult == DialogResult.Yes)
            {
                this.Validate();
                this.employer_ContactsBindingSource.EndEdit();
                this.tableAdapterManager.UpdateAll(this.clientEmployerDataSet);
                MessageBox.Show("Your action has been successful");
            }
        }

The error taking place on the "this.tableAdapterManager.UpdateAll(this.clientEmployerDataSet);" line.

You need to add the column you are looking at in the first pair of empty quotes in parameters.add

it should read:
