I have a class(dll) that extends winform datagrid to provide link column in vb.net. I have managed to create a datagrid in c# winforms that shows link in one of the column but when I try to create a EventHandler I get a compilation error:
"Method 'DataGridLink.F orm1.cs_LinkCli cked does not match delegate"
can anyone please help?
Thanks for all the help.
here is my code:
