if i set ID of the linkbutton(within repeater) as ID='<%# Eval("Questionnumber") %>' , i face problem when i intend to write the coding as repeater1.Items[].Findcontrol("lnkbtn")

Why you want to put question number value into link button id? (Note that in templated controls such as repeater, html ids would be anyway different). If you need to identify linkbutton for question number then CommandArgument property of linkbutton would be a correct choice.

I've did this for dynamically generated controls. You can prefix a tag such as LinkButton_X. You can override the ondatabinding for each element and set the id there OR you could use the databinding syntax with a method and a static seed generator, i.e a static int that is looped.
