I have two dropdowns select task and other select sub task....when i select sub task based on the selected task category it retains on the dropdown...for that i changed the ViewStateMode to enabled....However when i click on my submit button it takes the first value from the sub task dropdown and fills the database with those values....

taskDrpDown- ViewStateMode: Enabled Autopostback: True
subTaskDrpDown - ViewStateMode: Enabled AutopostBack: False

also page_load has(!IsPostback){//code}

populateCategory{//code}

taskDrpDown_SelectedIndexedChanged{//populateSubCategory}

populateSubCategory{//code}

submit_click{//code to submit all the entries to database}

Am i going wrong somewhere with the postback and all.....??

Please Help!!

Thanks in advance!

Solution 1

check if you are binding values to taskDrpDown after submit button click.
Your drop-down list is getting rebound and hence it would not able able to retain the selected value.

you should just set the dropdownlist.selecteditem =previously selected item

Solution 2

Put if statement on page load where you are binding these dropdowns like below

if(!IsPostBack)
{
//Bind Code of dropdown1
//Bind Code of dropdown2
}
