Add columns in listview in c#.net

listview column issue

From stackoverflow

• Use ListView.Columns.Add()

  peter : this is the simplest way i already mentioned in my question,,but here in my project they r doing some other way

  Clement Herreman : I assume you use this sytem at work, so why don't you just ask the person that designed it ? Did he left ?

• The line

  this._listAvailable = new leaf.Plugins.leafListView();
  

  implies that your control is derived from ListView (in fact, we can't know that for sure, it could be a whole other class with a similar api).
  This makes every answer you'll get speculative - it's possible your class behaved differently than a ListView (for example, it might change some methods or properties)

  peter : exactly i added those code also in our questions ,,but i didnt get anything

• The problem is simple actually everything is coming.the reason why its not coming at runtime we are referring the old DLL not the new DLL ,,,then how should it come,,sorry to disturbing you guys
