Getting <select> value when selected index was changed

Geni Lou

How can I get the value in server side of selected 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:

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.
