check boxes in datagrid

i want to use check boxes in datagird
the following code is VB
i tried converting the code in C#
but it is giving errors

1:Class is found when variable is expected
for Label
strStoreName = CType(myDataGridItem.FindControl("lblStoreName"), Label).Text

2:
Object reference not found

if(chkSelected.Checked)

the code works perfectly fine in VB
