c# - WPF: Programatically adding a ContextMenu to a DataGrid column header -

i'm trying add individualized , separate contextmenus each column header in project, when user right-clicks header, menu of checkboxes relates header appear allows them filter data.

a couple of catches: project i'm working on needs developed .net 4.0, , such don't have access datagridcolumnheader class introduced in .net 4.5. also, of needs done programatically, no xml allowed, of column data determined @ runtime.

i found similar stack question in done using xml, , i've sucessfully reproduced in xml, i'm new wpf , haven't been able reproduce programatically.

i've pasted c# code below think setup should occur.

    /// <summary>     /// function adds of columns default setup     /// </summary>     public void makeallcolumns()     {         (int = 0; < allcolumndisplaynames.length; i++)         {             datagridtextcolumn col = new datagridtextcolumn();             col.header = allcolumndisplaynames[i];             col.binding = new binding(allcolumnbindings[i]);             cangrid.columns.add(col);              // code addding context menus go here           }     } 

datagridcolumns not frameworkelements not have contextmenu. since want in code behind specifying data template column can pain (imho). try passing in frameworkelement header object column , set context menu on framework element.

example:

//...      datagridtextcolumn col = new datagridtextcolumn();      //...      textblock txt = new textblock() { text = allcolumndisplaynames[i] };     txt.contextmenu = new contextmenu(); // build context menu here.      col.header = txt;      //...
