I am having a drop down which contaion semester as its values. Its a component of admin panel so i want to maintain the previously selected drop-down value. How can i do this in ASP.Net. I have done this in PHP but i am new to ASP.net so please help me.

Being precise : suppose i have selected Semester-2 then every time I reload the page the default value semester-2 in the drop-down should come.

It is built-in to ASP.Net that after postbacks the value is maintained. If you are talking about refreshing the page then you'll need to store it in the Session and set it on PageLoad.

You mean to keep selected value same throughout the application? Unless it is changed manually. Right?

Is the dropdown list bound to a database?

no, i have inserted values statically. Which property should i use to retain session value by default

Not sure whether it is a good method, but try enabling autopostback. It seems to retain the selected value on page refresh with autopostback enabled.

In DropDownlist selectedindexchanged event store the selected value in session as;

C#

Session["DDSelectedValue"] = YourDropDownlistID.SelectedValue;

Now it depends upon you to set the value from session. If the admin panel is user control or on master page etc.

To set the value whenever you bind the dropdownlist use:

C#

YourDropDownlistID.SelectedValue = Session["DDSelectedValue"].ToString();

for further clarification post your code.
