This is c# code:
DropDownList ddl;
ddl.Items.Insert(0, new ListItem("--Select Me--", "0"));
ddl.Items.Insert(1, new ListItem("I'm the first", "1"));
ddl.Items.Insert(2, new ListItem("I'm the second", "2"));
ddl.Items.Insert(3, new ListItem("I'm the third", "3"));
Is there a way we can avoid these sequential insert into dropdownlist and bulk insert these values?
You can do this:
DropDownList ddl;
var ls=new List<KeyValuePair<int,string>>()
{
new KeyValuePair<int,string>(0,"--Select Me--"),
new KeyValuePair<int,string>(1,"I'm the first"),
new KeyValuePair<int,string>(2,"I'm the second"),
new KeyValuePair<int,string>(3,"I'm the third"),
};
ddl.DataTextField="Value";
ddl.DataValueField="Key";
ddl.DataSource=ls;
ddl.DataBind();
Use the AddRange method:
DropDownList ddl;
ddl.Items.AddRange(new ListItem[] { new ListItem ("--Select Me--", "0"), new ListItem("I'm the first", "1"), new ListItem("I'm the second", "2"), new ListItem("I'm the third", "3")});
This might be helpful:
List<ListItem> items = new List<ListItem>();
items.Add(new ListItem("Alabama", "Alabama"));
items.Add(new ListItem("Alaska", "Alaska"));
DropDownList1.Items.AddRange(items.ToArray());
DropDownList ddl = new DropDownList();
ddl.Items.AddRange(new[]
{
new ListItem("--Select Me--", "0"),
new ListItem("I'm the first", "1"),
new ListItem("I'm the second", "2"),
new ListItem("I'm the third", "3")
});
try this
ddl.Items.Add(new ListItem("--Select Me--", "0"));
ddl.Items.Add(new ListItem("I'm the first", "1"));
ddl.Items.Add(new ListItem("I'm the second", "2"));
ddl.Items.Add(new ListItem("I'm the third", "3"));
