Open vs test did not find can directly trigger the DataGridViewComboBoxCell in the ComboBox in the value of the event, depressed for half a day, look closely at MSDN there is a solution to the example, all blame themselves did not look carefully:

You first need to trigger the first event: currentcelldirtystatechanged

And calling the Datagridview.commitedit method in the event [about Commitedit MSDN explains the following: commits the changes in the current cell to the data cache, but does not end the edit mode. ]

So that the event that we care about cellvaluechanged can be triggered smoothly.

Call the following MSDN the source code provided for this workaround is for reference only:)

This event handler manually raises the Cellvaluechanged event//by calling the Commitedit method.void datagridview1_cur Rentcelldirtystatechanged (object sender, EventArgs e) {if (datagridview1.iscurrentcelldirty) {Datagridvie W1.    Commitedit (Datagridviewdataerrorcontexts.commit); }}//If A check box cell is clicked, this event handler disables//or enables the button in the same row as the clicked cell.public void Datagridview1_cellvaluechanged (object sender, DataGridViewCellEventArgs e) {if (datagridview1.colum Ns[e.columnindex]. Name = = "checkboxes") {DataGridViewDisableButtonCell Buttoncell = (datagridviewdisablebuttoncell) dat            AGridView1. Rows[e.rowindex].        cells["Buttons"];            Datagridviewcheckboxcell Checkcell = (Datagridviewcheckboxcell) dataGridView1. Rows[e.rowindex].        cells["checkboxes"]; buttoncell.enabled =!        (Boolean) Checkcell.value;    Datagridview1.invalidate (); }}
