Question

I have a datagridview with multiple checkboxes. When the Finished checkbox is checked I need to execute linq code to update a specific table. How do I find out if that specific check box is dirty and where do I write the code to pass the values I need to be passed to the table. Note that it is not the same table that the datagridview is based on.

Thanks.

EDIT:

 private void propertyInformationDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
    {
        DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)propertyInformationDataGridView.Rows[e.RowIndex].Cells[3];

        DataGridViewRow row = propertyInformationDataGridView.Rows[e.RowIndex] as DataGridViewRow;

        System.Data.DataRowView SelectedRowView;
        newCityCollectionDataSet.PropertyInformationRow SelectedRow;

        SelectedRowView = (System.Data.DataRowView)propertyInformationBindingSource.Current;
        SelectedRow = (newCityCollectionDataSet.PropertyInformationRow)SelectedRowView.Row;

        if (Convert.ToBoolean(checkCell.EditedFormattedValue) == true)
        {
            DataClasses1DataContext dc = new DataClasses1DataContext();

            var matchedCaseNumber = (from c in dc.GetTable<PropertyInformation>()
                                     where c.CaseNumberKey == SelectedRow.CaseNumberKey
                                     select c).SingleOrDefault();

            reportsSent newReport = new reportsSent();
            newReport.CaseNumberKey = SelectedRow.CaseNumberKey;
            dc.reportsSents.InsertOnSubmit(newReport);
            dc.SubmitChanges();

        }
    }

Do I need to endedit at some point is that the issue?

This is from some of my code, all you need to do is create a “CellContentClick” event for your datagridview.

The easiest way to do this is select the Datagridview, go to properties and click on the lightning bolt. Scroll down to “CellContentClick” and double click in the empty box. This will auto generate the method you need to paste the following code into.

Make sure you rename my instances of “CustomersDataGridView” to whatever yours is named as well, intellisense should highlight invalid code in red that you need to replace.

Also, the “9” you see in the checkCell declaration needs to be changed to the index of your “Finished” check-box. If it is in the 3rd cell from the left, put a 2 there instead of a 9, as the indexing is 0 based.

EDITTED to fix comments:

private void CustomersDataGridView_CellContentClick(object sender, DataGridViewCellEventArgs e)
{

    if (e.ColumnIndex.ToString() == "9")
    {
        DataGridViewCheckBoxCell checkCell = (DataGridViewCheckBoxCell)CustomersDataGridView.Rows[e.RowIndex].Cells[9];
        DataGridViewRow row = CustomersDataGridView.Rows[e.RowIndex] as DataGridViewRow;

        if (Convert.ToBoolean(checkCell.EditedFormattedValue) && CustomersDataGridView.IsCurrentCellDirty)
        {
            //Do Work here.
            var z = row.Cells[0].Value; // Fill in the brackets with the column you want to fetch values from
            //z in this case would be the value of whatever was in the first cell in the row of the checkbox I clicked
        }
    }
}
