Hello Geni, Try below: JavaScript Python C++ Java protected void language_SelectedIndexChanged(object sender, EventArgs e) { string selectedValue = language.SelectedValue; // Do something with the selected value here } In this example, language is the ID of the dropdown list control on your webform. The SelectedIndexChanged event is wired up to this control using the OnSelectedIndexChanged attribute in the HTML markup, like this: Thanks Naimish Makwana

If you want in Webform use below code: //Assuming your dropdown is like below //In code behide file add below event protected void myDropDownList_SelectedIndexChanged(object sender, EventArgs e) { string selectedValue = myDropDownList.SelectedValue; // Do something with the selected value } Note that the SelectedIndexChanged event handler will only be called if the AutoPostBack property of the DropDownList is set to true .
