Asp.NET DropDownList SelectedItem.Value not changing
asp.net, c#, data-binding, drop-down-menu, selectedvalue
Solution
If you're databinding in `Page_Load`, you're essentially also resetting the SelectedItem.
You should wrap whatever binding code that exists in `Page_Load` inside an `if(!IsPostBack)` block.
if(!Page.IsPostBack)
{
// Your binding code here ...
}
Problem
markup: ``` <div style="float:left;margin-top:15px;width:80px"> <asp:DropDownList ID="MyList" runat="server" Width="100px"></asp:DropDownList> </div> ``` code: ``` // clear vehicles list MyList.Items.Clear(); // add 'all' option MyList.Items.Add(new ListItem("ALL", "0")); // add assets foreach (CustomClass item in items) MyList.Items.Add(new ListItem(item.Name, item.ID.ToString())); ``` No event triggering for SelectedIndexChanged since it's not necessary. When I click the button for postback, the value of the selecteditem remains the value of the first item in the DropDownList. What am I missing? NOTE Please stop replying and editing posts.
