C # Winform prevents users from adjusting ListView column Widths _c# tutorial

Copy Code code as follows:

Events: When the column width is changed
private void Columnwidthchange (object sender, Columnwidthchangingeventargs e)
{
If you're not adjusting to the first column, you don't care.
if (E.columnindex > 0) return;
Cancel the event that is being adjusted
E.cancel = true;
Restore the new width to its previous width
E.newwidth = This.lvstudents.columns[e.columnindex]. Width;
}

The purpose of this code is to make it impossible for the user to adjust the width of the first column, and of course you can change it to something else, or you can use the column name as a qualifying condition. let you play it. Finally, let ListView's Columnwidthchanging event invoke this event on the line.
