Of course you can use a dropdown list in a datalist, you just can't do
it without writing a little code.
All you need to do is put a little code in the ItemDataBound event of the list.
Something like this...
private void DataList1_ItemDataBound(object sender,
System.Web.UI.WebControls.DataListItemEventArgs e)
{
DropDownList ddl = null;
DataRowView drv;
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType ==
ListItemType.AlternatingItem)
{
drv = (DataRowView)e.Item.DataItem;
ddl = (DropDownList)e.Item.FindControl("ddlStates");
BindStateDropDown(ddl);
//Set current value
ddl.SelectedValue = drv["ID"] + "";
}
}
private void BindStateDropDown(DropDownList ddl){
ddl.DataSource = FunctionThatReturnsDataTableWithStates();
ddl.DataTextField = "StateName";
ddl.DataValueField = "ID";
dll.DataBind();
}
Just remember to set the ItemDataBound handler, usually in InitializeComponent()
this.DataList1.ItemDataBound += new
System.Web.UI.WebControls.DataListItemEventHandler(this.DataList1_ItemDataBound);
And when the grid binds, you'll fill the dropdown list.
