  How to access value of dropdownlist in detailsview (template

  Jan 07, 2015 02:15 PM|Ravar33|LINK

  Hi

  I've created a detailsview with regular textfield inputs. Below those regular inputs I have 1 dropdownlist, which I've added using templates.

  I can access the regular fields using the "edit field" window (via smarttag) and then give a Datafieldname to that textfield. But there is no "Datafield' option for the dropdownlist. 

  How do I get the value of my dropdownlist to the function of my app-code class?

  For pictures and the same question:  http://stackoverflow.com/questions/27825739/how-to-access-value-of-dropdownlist-in-detailsview-template

  To bind ddl to detailsview datasource you can bind ddl selectedvalue property

  SelectedValue = '<%# Bind("FK_RestaurantNr") %>'

  To populate dropdown items, you can add ddldatasource then set datatextfield and datavaluefield

  Hi Ravar,

  Thanks for your post.

  You could refer to the following sample.

  <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" AutoGenerateRows="false" OnDataBound="DetailsView1_DataBound">
      <Fields>
          <asp:TemplateField HeaderText="Restaurantnaam">
              <ItemTemplate>
                  <asp:DropDownList ID="ddl" runat="server" DataTextField="Restaurantnaam" DataValueField="ID"></asp:DropDownList>
              </ItemTemplate>
          </asp:TemplateField>
          <asp:TemplateField HeaderText="Naam recensent">
              <ItemTemplate>
                  <asp:TextBox ID="txtnaam" runat="server" Text='<%#Eval("Naamrecensent") %>'></asp:TextBox>
              </ItemTemplate>
          </asp:TemplateField>
          <asp:TemplateField HeaderText="Datum recensie">
              <ItemTemplate>
                  <asp:TextBox ID="txtdatum" runat="server" Text='<%#Eval("Datumrecensie") %>'></asp:TextBox>
              </ItemTemplate>
          </asp:TemplateField>
          <asp:TemplateField HeaderText="Beoordeling">
              <ItemTemplate>
                  <asp:TextBox ID="txtbeoordeling" runat="server" Text='<%#Eval("Beoordeling") %>'></asp:TextBox>
              </ItemTemplate>
          </asp:TemplateField>
          <asp:TemplateField HeaderText="Score">
              <ItemTemplate>
                  <asp:TextBox ID="txtscore" runat="server" Text='<%#Eval("Score") %>'></asp:TextBox>
              </ItemTemplate>
          </asp:TemplateField>
      </Fields>
  </asp:DetailsView>

  What does OnDataBound do exactly? I'm currently trying this, but an error occurs when I run this. 

  The error:

  "ASP.AllRecensies_aspx doesn't contain a definition for DetailsView_Databound"

  So what code should I put in "DetailsView_Databound"?
