Checkbox column problem
-
Hi, I have a windows forms app that contains a datagridview, with two filtered columns, some textbox columns, and a checkbox column. The filtering on the dgv is accomplished by using dropdowns on the column headers of the two filterable headers and this happens reasonably quickly. My problem comes when I try to set the value of all the checkboxes to either checked or not checked. If I have a small number of rows in the dgv then each check operation takes about .0015 of a second. If I have a large number of rows that time jumps to 1.5 seconds per row. When I use the filters the dgv updates in about 2 seconds. I am at a loss. The code I use to update the dgv checkbox column is:
If btnSelectRecords.Text = FormConstants.ControlConstants.DESELECT_ALL_RECORDS Then For Each row As DataGridViewRow In dgvLoanRecords.Rows row.Cells(FormConstants.GridViewConstants.SELECTED).Value = False Next btnSelectRecords.Text = FormConstants.ControlConstants.SELECT_ALL_RECORDS Else For Each row As DataGridViewRow In dgvLoanRecords.Rows row.Cells(FormConstants.GridViewConstants.SELECTED).Value = True Next btnSelectRecords.Text = FormConstants.ControlConstants.DESELECT_ALL_RECORDS End IfCan someone point me in the right direction to speed this process up. Thanks Jim
