RadioButtonList.SelectedIndexChanged not raised when the ListItem has Selected="True" not working on IE8

I have problem with radiobuttonlist.

I have two radiobuttons in radiobuttonlist and based on selection, i am enabling and disabling the text box.

First time i used date radiobutton and i took date in corresponding textbox and i saved it into database and then when i came back on same page i saw the date radiobutton is checked has proper value then i clicked on another radiobutton and this time page is postback and clear my all the data which was in my other controls(I have 5-6 text boxed on my page). I dont know why?, It supposed to select my other radiobutton and enable the corresponding text box

On firefox it is working fine.

This is my code:-

Tooltip="Please select either Expiration (In Days) or Expiration Date "
Height="42px" Width="167px">

ToolTip="Number of days until this credential will expire after submission"
Width="40px" ValidationGroup="vModifyCredType">

Display="Dynamic" ErrorMessage="Expiration (in days) is required." Font-Size="8pt"ValidationGroup="vModifyCredType">
Display="Dynamic" ErrorMessage="Please enter an integer value greater than 0 and less than 10,000."
Font-Size="8pt" SetFocusOnError="True" Type="Integer" MinimumValue="0" MaximumValue="9999"
ValidationGroup="vModifyCredType">

Display="Dynamic" ErrorMessage="Expiration date is required." Font-Size="8pt"
ValidationGroup="vModifyCredType">
Format="MM/dd/yyyy" CssClass="smcalendar" Enabled="True" />
Display="Dynamic" ErrorMessage="Invalid date. Select a date or enter in the format mm/dd/yyyy"
Font-Size="Small"
ValidationExpression="([1-9]|0[1-9]|1[012])[- /.]([1-9]|0[1-9]|[12][0-9]|3[01])[- /.](19|20|21|22|23|24|25)\d\d">

Hi Koti,
If you make autopostback="False" , when you click on another radio button , there is no function at all, it supposed to enable the corresponding text box so that you can write some value and save in the database.
