dropdownlist....


Thank you for your reply.
yes I used the code which u just sent it to me but it crashes again.
let me explain the problem.
when user go to the one Item in the drop down list , it works as well but 
when they want to change the item , it crashes and we get the error base 
of index is out of range or Specified cast is not valid which is more 
common.
but something else, when the user goes to the first item in the 
dropdownlist SELECT A TYPE, it works ... it means ,They can choose another 
item through the dropdownlist as well.
can you provide me by ur email? I can send you the page to see what is the 
matter with this code... 
mine is Anirose_us@y...

again thank you ...pls be in touch





> Well Anirose...
	See ViewState will just maintain the Item values inside the 
dropdown
even after u post back and u wont need to rebind the dropdown again to get
the values... do u add the items in the dropdown during runtime from db or
while developing... if u are doing thro code then check if u have done this
as below
		Private Sub Page_load()
			If !(Me.IsPostBack) then
				... Now Append the dropdwon with values 
from
DB....
				.. all the code goes here....
			EndIf
		End Sub

One more is that see if u have checked the 'AutoPostBack' property of the
dropdown to true... all the above code goes only if this property is
true.... else even if u change the selected item in dropdown no value will
be posted to the server....

Or can u be more specific on 'crash'.. what happens exactly.....

keep me posted of issues.....

hi friends,


I have a dropdownlist which works as well but when users want to change 
the item, it crashes ... I know something related to view state might 
effect on it but how can I add a code in the sub below to get ride of 
that ? pls help me ...

private void lstExhibitTypes_SelectedIndexChanged(object sender, 
System.EventArgs e)
		{
// TODO Add code to clean up child viewstate so that one page type--> 
another won't cause crash
				
		}

Thank you ;)
