The following describes a DataGridView Winform DataGridViewCheckBoxColumn in use:

 

DataGridViewCheckBoxColumn the CheckBox is selected or

　　In determining the DataGridView CheckBox selected column when [0] exist with DataGridViewRow.Cells .FormattedValue.ToString () == "True" when the statement is a problem, when we click on CheckBox, the results show is not selected, but if we click when other cells, the results show selected. And with DataGridViewRow.Cells [0] .EditedFormattedValue.ToString () == "True" when the statement is selected by the state anyway.

Why is there such a result?

　　The reason: that is the result of the operation FormattedValue submitted, and EditedFormattedValue is the current result, regardless of whether the results have been submitted.

　　　　　Therefore, the use DataGridViewRow.Cells [0] .EditedFormattedValue.ToString () == "True" Analyzing select suitable

DataGridViewCheckBoxColumn set the CheckBox checked by default

　　 ((DataGridViewCheckBoxCell)dgvDownloadList.Rows[i].Cells["Column1"]).Value = true;

 

DataGridViewCheckBoxColumn the first time to get checked in CheckBox

　　When you click a checkbox or cancel datagridview column, the more difficult to obtain its status is checked or unchecked, then good for other operations, the following list of its solution: 

　　CommitEdit: will be submitted to the current cell changes to the data cache without ending edit mode
