Hi,
I have two drop down list. On each of these drop down's selection some code is there.
But page is taking too much time to call these events.
I have checked this within updatepanel and without updatepanel, but the result is same. How can I minimize the loading time.
Not : - 1st drop down has only 3 items and 2nd has only 4 items.

Total viewstate size - more than 300k

can you post your markup and codebehind please? so we can see whats actually going on.
TheCoolCoder 10-Oct-12 7:26am
   
CustomAttribute class is missing in the code. Anyway one thing you have done wrong clearly is nesting of tables, nested tables always increases the load and should be only be used when absolutely necessary.
I.explore.code 10-Oct-12 7:54am
   
Can you check whats the value set on EnablePartialRendering property of the ToolkitScriptManager?
itskvini 10-Oct-12 8:45am
   
not set, so its true
I.explore.code 10-Oct-12 8:49am
   
ok this might sound too onerous, but can you change all the tables to divs? not sure if that is causing the problem, but divs are much easier and flexible to work with. Using tables is anti-web these days.
ZurdoDev 10-Oct-12 8:20am
   
Step through the code and see what is so slow.
itskvini 10-Oct-12 8:47am
   
I have checked. Everything seems to be working properly, the issue is the event itself is getting called after very long time.
ZurdoDev 10-Oct-12 8:52am
   
Then it may be the complexity of the html, too much, as gladiatron mentioned. Too many tables.
