Question

I have 2 dropdownlists, the 1st dropdownlist is bind to the second dropdownlist. If the second dropdownlist has only one item, this item cannot be selected and hence any function cannot be triggered. I went to any related answers that have already been uploaded…but it didn’t help… It’s important. Can someone help me out in this issue?

Answer 1

Just add a default ListItem to your second dropdown.

Eg.

<asp:ListItem Text="--Select--" Value="-1"></asp:ListItem>

You can add from c# also: Write this after you have populated dropdownlist from your datasource.

DropDownList1.Items.Insert(0, new ListItem("--Select--", "-1"));
