Populating dropdownlists through LINQ based on a selection from another dropdownlist

[moto11]

I have been working on this and it works. However after attempting to change my option from the controlling dropdownlist to see another list in the dropdown that should show my dynamic list, nothing happens. It still shows the previous list. Could i get some help with this?:Here is my Front side: \[code\] <label for="ddlGift1">Gift #1</label> <aspropDownList runat="server" ID="ddlGift1" class="gift" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" OnSelectedIndexChanged="ddlGift1_SelectedIndexChanged"> <asp:ListItem Value="http://stackoverflow.com/questions/15642284/--" Text="Please Select" /> </aspropDownList> <label for="ddlFName1">Fund Name</label> <aspropDownList runat="server" ID="ddlFName1" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" > <asp:ListItem Value="http://stackoverflow.com/questions/15642284/--" Text="Please Select" /> </aspropDownList> <label for="ddlGift2">Gift #2</label> <aspropDownList runat="server" ID="ddlGift2" class="gift" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" OnSelectedIndexChanged="ddlGift2_SelectedIndexChanged" > <asp:ListItem Value="http://stackoverflow.com/questions/15642284/--" Text="Please Select" /> </aspropDownList> <label for="ddlFName2">Fund Name</label> <aspropDownList runat="server" ID="ddlFName2" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" > <label for="txtPAmount2">Pledge Amount</label> <asp:TextBox runat="server" ID="txtPAmount2" CssClass="narrow" text="0.00" onClick="ComputeCosts();" ClientIDMode="Static" class="PAmount" /> <label for="ddlGift3">Gift #3</label> <aspropDownList runat="server" ID="ddlGift3" class="gift" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" OnSelectedIndexChanged="ddlGift3_SelectedIndexChanged"> <asp:ListItem Value="http://stackoverflow.com/questions/15642284/--" Text="Please Select" /> </aspropDownList> <label for="ddlFName3">Fund Name</label> <aspropDownList runat="server" ID="ddlFName3" AutoPostBack="true" AppendDataBoundItems="True" ClientIDMode="Static" > <asp:ListItem Value="http://stackoverflow.com/questions/15642284/--" Text="Please Select" /> </aspropDownList>\[/code\]Backside:Example of one function:\[code\]private void SetCOB(DropDownList name) { var _db = (from a in _foundation.COB orderby a.id select new { a.id, a.name }); name.DataSource = _db; name.DataTextField = "name"; name.DataValueField = "id"; name.DataBind(); } protected void ddlGift1_SelectedIndexChanged(object sender, EventArgs e) { if(ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="41") { SetCOB(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="42") { SetCOLA(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="43") { SetCONHP(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="44") { SetOE(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="45") { SetCSEE(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="52") { SetA(ddlFName1); } else if (ddlGift1.SelectedValue =http://stackoverflow.com/questions/15642284/="54") { SetS(ddlFName1); } } protected void ddlGift2_SelectedIndexChanged(object sender, EventArgs e) { if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="41") { SetCOB(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="42") { SetCOLA(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="43") { SetCONHP(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="44") { SetOE(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="45") { SetCSEE(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="52") { SetA(ddlFName2); } else if (ddlGift2.SelectedValue =http://stackoverflow.com/questions/15642284/="54") { SetS(ddlFName2); } } protected void ddlGift3_SelectedIndexChanged(object sender, EventArgs e) { if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="41") { SetCOB(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="42") { SetCOLA(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="43") { SetCONHP(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="44") { SetOE(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="45") { SetCSEE(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="52") { SetA(ddlFName3); } else if (ddlGift3.SelectedValue =http://stackoverflow.com/questions/15642284/="54") { SetS(ddlFName3); } }\[/code\]
