Inline editing of gridview with dropdownlist

[AhsanS]

Hello Fellows, i am having a problem while trying to bind the dropdown list in gridview. i am able to fill the dropdown. But my problem is that i am updating the gridview without postbacks. i mean to say the update command is written in the sqldatasource. Can any body tell me how can i bind the dropdownlist? For textbox we use Bind("columnname"). any help is highly appreciated Thanks in advance. Ahsan Ullah
