button does not Postback

[Ganesh Raju via .NET 247]

Hi,

I have a dropdownlist and a button on my aspx page. If i havemore than 90 items in the dropdownlist my button does not dopostback. If there are less than 80 items in the dropdownlist,same button does postback now. I couldnt understand what isgoing on, can someone please help.

I tried to set the 'enableviewstate' property to false, then thebutton can do the postback, but the dropdownlist can notremember the selection.

Thanks so much!!!
Ganesh
