winforms - C#: Datagridview not displaying the data -

i working on winforms application. on form drag , drop datagridview control , set of properties using properties window. following code using populate datagridview. wrote code inside constructor.

list<mycustomclass> lst = new list<mycustomclass>(); lst = loadlist(/*some params here*/);//now uptil point works i.e list contains values desribed. datagridview1.datasource = lst; 

the problem when run program nothing displayed in datagridview.

for more details following code represents properties set using properties window

        this.datagridview1.allowusertoaddrows = false;         this.datagridview1.allowusertodeleterows = false;         this.datagridview1.allowusertoresizerows = false;         this.datagridview1.anchor = ((system.windows.forms.anchorstyles)(((system.windows.forms.anchorstyles.top | system.windows.forms.anchorstyles.left)                     | system.windows.forms.anchorstyles.right)));         this.datagridview1.autosizecolumnsmode = system.windows.forms.datagridviewautosizecolumnsmode.fill;         this.datagridview1.backgroundcolor = system.drawing.color.white;         this.datagridview1.columnheadersheightsizemode = system.windows.forms.datagridviewcolumnheadersheightsizemode.autosize;         this.datagridview1.gridcolor = system.drawing.color.white;         this.datagridview1.location = new system.drawing.point(2, 329);         this.datagridview1.margin = new system.windows.forms.padding(2);         this.datagridview1.multiselect = false;         this.datagridview1.name = "datagridview1";         this.datagridview1.rowheadersvisible = false;         this.datagridview1.selectionmode = system.windows.forms.datagridviewselectionmode.fullrowselect;         this.datagridview1.size = new system.drawing.size(334, 106);         this.datagridview1.tabindex = 0; 

add code before assigning datasource , should fine

datagridview1.autogeneratecolumns = true; 

edit

also check if have public properties used display contents of class columns in datagridview
