C＃DataGridView禁用列标题中的排序图标

Question

I have a Winforms DataGridView with few columns which can be sorted and few which couldn't be. For columns which I don't want my gridview to be sorted I have set

dgvConnections.Columns[e.ColumnIndex].SortMode = DataGridViewColumnSortMode.NotSortable; in

dgvConnections_ColumnHeaderMouseClick event handler but I am unable to get rid of the the sort icon from the column header, as its presence could cause confusion to the user.

So kindly suggest me a way to get rid of the sorting icon from the column which cannot be sorted. Thanks in advance!

Answer 1

It looks like you are not maintaining the correct execution order. The code you wrote will do the work

dgvConnections.Columns[e.ColumnIndex].SortMode = DataGridViewColumnSortMode.NotSortable;

but make sure you are calling it after initializing the DataGridView.

If you want it for specific columns like you mentioned in your question, you need to find the index and set the sortmode.
