使用下拉列表中的值自动填充Detailsview插入文本框

Question

I am trying to auto populate the textbox for the field clientId while the detailsview is in insert mode.

It needs to end up like this... http://s7.postimg.org/o7d48cfvv/Untitled.png

name *textbox*
address *textbox*
phone *textbox*
email *textbox*
clientId *AUTOPOPULATED* - based on dropdownlist1.value

I looked around and couldnt find a solution anywhere.

Thanks!

to achieve this you need to make the last field(clientId) on your detailsview control as a template field and then set the value of InsertItemTemplate to the value of drop down list, here is an example for you:

your .aspx web form: //eg this is your dropdown list

  <asp:DropDownList ID="DropDownList1" runat="server"> <asp:ListItem>id1</asp:ListItem> <asp:ListItem>id2</asp:ListItem> <asp:ListItem>id3</asp:ListItem> </asp:DropDownList> 

//eg your detailsview control

  <asp:DetailsView ID="DetailsView1" runat="server" Height="50px" Width="125px" DataSourceID="SqlDataSource1" AutoGenerateRows="False"> <Fields> <asp:BoundField DataField="Firstname" HeaderText="Firstname" SortExpression="Firstname" /> <asp:BoundField DataField="Address" HeaderText="Address" SortExpression="Address" /> <asp:BoundField DataField="Suburb" HeaderText="Suburb" SortExpression="Suburb" /> <asp:BoundField DataField="State" HeaderText="State" SortExpression="State" /> <asp:BoundField DataField="Postcode" HeaderText="Postcode" SortExpression="Postcode" /> <asp:BoundField DataField="MPhone" HeaderText="MPhone" SortExpression="MPhone" /> <asp:TemplateField HeaderText="Username" SortExpression="Username"> <EditItemTemplate> <asp:Label runat="server" Text='<%# Eval("Username") %>' ID="Label1"></asp:Label> </EditItemTemplate> <InsertItemTemplate> <asp:TextBox runat="server" Text='<%# DropDownList1.SelectedItem.Value %>' ID="TextBox1"></asp:TextBox> </InsertItemTemplate> <ItemTemplate> <asp:Label runat="server" Text='<%# Bind("Username") %>' ID="Label1"></asp:Label> </ItemTemplate> </asp:TemplateField> <asp:CommandField ShowInsertButton="True"></asp:CommandField> </Fields> </asp:DetailsView> 

so when you select a value from the dropdownlist above and click on new command on your detailsviewcontrol it will pickup the value from the list and bind it to the textbox as a value, like the snapshot below:
