I found a code to display a winform by double click a cell in a DataGridView
I can not find
I built this piece of code StageDetail class
not run
///// public struct StageDetail { private bool _xlogico; private string _xcadena; private int _xnumero; public StageDetail(bool xlogico, string xcadena, int xnumero) { this._xlogico=xlogico; this._xcadena=xcadena; this._xnumero=xnumero; } public bool XlogicO {get{return _xlogico;}} public string XcadenA {get{return _xcadena;}} public int XnumerO {get{return _xnumero;}} }
public StageDetail StageDetails=new StageDetail();
///
if you help me to publish source code with the same characteristics
