Did you do this far, again under the divergent thinking about, give you an idea:
Custom user controls and user controls and then put a fixed size of the panel, the user control properties with rows of data binding, throw all the checkbox to the user controls on a panel, events can literally;;
Datagridview don't have a a checkbox added;; Just add a user control,,, and then the column width change (redraw?) Changes the size of the user control;

CodePudding user response:

The WPF good implementation, with this, it's too difficult

CodePudding user response:

Then at your code, you this redraw method is not suitable, just draw out, no Mao Yong;
Need examples of control, then control assigned to the corresponding position

Implement a DataGridViewCheckboxListColumn and DataGridViewCheckBoxListCell,
