Dec 30th, 2008
Hi all,

I am trying to select a value from drop down list and if the value is NewDepartment then a text box should be visible for adding a new value and that value must be populated in the drop down list also if the user selects the new value then that value should also be stored into the database.

How can we do that?
I did write few lines of code but i am getting errors.My code goes here
ASP.NET Syntax (Toggle Plain Text) 
  1.         Dim k As String
  2.         If ddldept.SelectedItem = NewDepartment Then
  3.             txtdept.Text = Visible
  4.             k = txtdept.Text.ToString()
  5.             ddldept.SelectedItem.Equals(k)
  6.         End If

I am getting an error at NewDepartment saying that NewDepartment is not declared.

Any help is greatly appreciated.
Thanks in advance,
Karthik.

Try this:

If (ddldept.SelectedItem.ToString() = "NewDepartment" ) Then
txtdept.Text = Visible
k = txtdept.Text.ToString()
ddldept.SelectedItem.Equals(k)
End If

Are you sure about the spelling of the selected item. Is it "NewDepartment" with no spaces in between words?

This code is working fine for me:

If I select the item 'NewDepartment' and click the button the textbox is becoming visible. As you can see i have written the code in the button click event. Is this you are looking for?

.aspx
ASP.NET Syntax (Toggle Plain Text) 
  1.  
  2. <asp:DropDownList ID="ddldept" runat="server" Style="z-index: 131; left: 242px; position: absolute;
  3.             top: 153px">
  4.             <asp:ListItem>Solutions</asp:ListItem>
  5.             <asp:ListItem>SA</asp:ListItem>
  6.             <asp:ListItem>Training</asp:ListItem>
  7.             <asp:ListItem>HR</asp:ListItem>
  8.             <asp:ListItem>Finance</asp:ListItem>
  9.             <asp:ListItem>Documentation</asp:ListItem>
  10.             <asp:ListItem>Quality</asp:ListItem>
  11.             <asp:ListItem>NewDepartment</asp:ListItem>
  12.         </asp:DropDownList>
  13.  
  14.         <asp:Button ID="Button2" runat="server" Text="Button" /></div>
  15.  
  16.  
  17.         <asp:TextBox ID="TextBox1" Visible="false" Text=""  runat="server"></asp:TextBox>

.aspx.vb

ASP.NET Syntax (Toggle Plain Text) 
  1. Protected Sub Button2_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button2.Click
  2.         If (ddldept.SelectedItem.ToString() = "NewDepartment") Then
  3.             TextBox1.Visible = True
  4.         End If
  5.     End Sub

top: 153px">
<asp:ListItem>Solutions</asp:ListItem>
<asp:ListItem>SA</asp:ListItem>
<asp:ListItem>Training</asp:ListItem>
<asp:ListItem>HR</asp:ListItem>
<asp:ListItem>Finance</asp:ListItem>
<asp:ListItem>Documentation</asp:ListItem>
<asp:ListItem>Quality</asp:ListItem>
<asp:ListItem>NewDepartment</asp:ListItem>
</asp: DropDownList>

.aspx.vb

Protected Sub ddldept_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddldept.SelectedIndexChanged
If (ddldept.SelectedItem.ToString() = "NewDepartment") Then
TextBox1.Visible = True
