Try replacing Eval with Bind:
Text='<%# Bind("ReportingTimeframe") %>'

If that doesn't solve the problem, then you'll need to explain what you mean by "not binding".

not binding - have to populate dropdown selected value in datagrid textbox column. textbox is not binding the dropdown value. (after deployment, it is showing just null value, when i click excel button, textbox is coming without values )
