[RESOLVED] [02/03] copy from one dropdownlist to another

[riteshjain1982]

I want to copy data from one dropdown list data to another one,Is it possible to do without loop?
This is how i am doing currently

   
           ddlSerchIn.Items.Insert(0, "Data1")
            ddlSerchIn.Items(0).Value = "Data1"

            ddlSerchIn.Items.Insert(1, "Data2")
            ddlSerchIn.Items(1).Value = "Data2"


           Dim lstItems As ListItem
            For Each lstItems In ddlSerchIn.Items
                ddlAdvSearch1.Items.Add(lstItems)
            Next

Check .Items.CopyTo function of DDL class. It returns an array of ListItem.

Dim lstItems As New ListItem[ddlSerchIn.Items.Count]
ddlSerchIn.Items.CopyTo(lstItems, 0)
 
ddlAdvSearch1.DataSource = lstItems
ddlAdvSearch1.DataBind()

Just wrote from top of my head.

Edit: changing language from C# to VB

One more point to be made:

If the first DDL is bound to a datasource, you can just retrieve its datasource, pass it to the other one and call DataBind() of second DDL.

 Dim lstItems As ListItem() = New ListItem(ddlSerchIn.Items.Count -1){}
 ddlSerchIn.Items.CopyTo(lstItems, 0)
 ddlAdvSearch1.AddRange(lstItems )
