DataGridViewCheckBoxColumn问题开始查看复选框是否已选中

Question

So this one sounds simple, but for the life of me I cannot see why this is not working (Windows Forms). Any help much appreciated.

I have a DataGridViewCheckBoxColumn set as per following;

DataGridViewCheckBoxColumn col = new DataGridViewCheckBoxColumn();
col.DataPropertyName = "Data";
col.Name = "DataName";
col.HeaderText = "Data Header";
DataGridView.Columns.Add(col);

This works and my grid allows users to change check/uncheck the checkbox. Great now when they press save, to save it to the db i have the following:

foreach (DataGridViewRow row in dgUsers.Rows)
{
 bool bData = (bool)row.Cells["Data"].Value;
}

To read teh checkbox, I have also tried .selected and also tried to view the checkbox cell. in the following ways:

DataGridViewCheckBoxCell cell = row.Cells["Data"] as DataGridViewCheckBoxCell;
DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)row.Cells["Data"];

However none of this works. I just want to get the boolean of if it true or false.

Any ideas.

Thanks

Answer 1

So after extensive research I think I may have found an answer. I have a datagridview with numerous data one of which is a checkbox cell so users can mark/unmark the data. Now because I have a button which will loop through the datagridview rows and save the changes to a database. There is a possibility that the checkbox has not fully committed the value change. Therefore we can use the edited value as follows:

DataGridViewCheckBoxCell.EditedFormattedValue

Gets the current, formatted value of the cell, regardless of whether the cell is in edit mode and the value has not been committed

. So for my example it would be the following:

DataGridViewCheckBoxCell cell = row.Cells["Data"] as DataGridViewCheckBoxCell;
bool bData = (bool)cell.EditedFormattedValue
