    Hi,

    I am trying to update GridView with the input of the user but getting exception when pressing on Update -

    "Data keys must be specified on GridView 'GridView1' before the selected data keys can be retrieved. Use the DataKeyNames property to specify data keys. "

    The Update statement I used is - UPDATETABLE_NAME SETCOLUMN1 = @COLUMN1

    Please help...
