My DropdownList SelectedItem need for Repeater DataSource.

My DropDownList and repeater Codes:

XML

<asp:DropDownList runat="server" ID="DropDateSelect" OnSelectedIndexChanged="DropDateSelect_SelectedIndexChanged" AutoPostBack="true">
                            </asp:DropDownList>
                            <asp:Repeater ID="rpttarihdetaylari" runat="server">
                                <ItemTemplate>
                                     <p class="name"><%#Eval("UcretTipi") %></p>
                                     <p class="date"><%#Eval("Ucret") %></p>
                                </ItemTemplate>
                            </asp:Repeater>

My SelectedIndexChanged Codes:

C#

if (!IsPostBack==false)
           {
               string deneme = DropDateSelect.SelectedItem.ToString();
               DateTime gelentarih = deneme.ToDateTime();
               string degercevir = gelentarih.ToString("yyyy-MM-dd");

               rpttarihdetaylari.DataSource = DataBase.Merkez.GetDataTable("Select UcretTipi,Ucret From TurGelismisUcret Where TurUcretSubID='" + YorumCs.yorumsubid + "' AND turbaslangictarihi='" + degercevir + "'");
               rpttarihdetaylari.DataBind();
           }

And DropDownList DataSource Bind Codes;

SQL

if (!IsPostBack == true)
           {
               DropDateSelect.DataSource = DataBase.Merkez.GetDataTable("Select turbaslangictarihi,tursubid from TurTarihleri where tursubid='" + YorumCs.yorumsubid + "'");
               DropDateSelect.DataTextField = "turbaslangictarihi";
               DropDateSelect.DataValueField = "tursubid";
               DropDateSelect.DataBind();
           }

Put a breakpoint on the very first line of your DropDateSelect_SelectedIndexChanged event. Does it get hit? Does the page appear to post back?

Page_Load will get hit first because it is posting back. Then it should hit your event.

Your code is vulnerable to SQL Injection[^].

NEVER use string concatenation to build a SQL query. ALWAYS use a parameterized query.
