ListView list controls display wrong data the 3rd time

muybn · August 11th, 2010, 03:17 AM

I have a ListView that populates and displays a user's data (via a profile system in VWD 2008) during Page_Load and also when I go from the EditItemTemplate to the ItemTemplate. Then when I go to the edit screen again, my DropDownList and RadioButtonList controls display the first items in the corresponding tables instead of the correct profile values. I don't understand why the controls populate correctly the first and second times but not on the third time (that's right, the third time is NOT a charm); I hope someone can help me understand how to solve this problem.

ItemTemplate:

Code:

 <asp:DropDownList ID="ddlTState" AppendDataBoundItems="True" DataSourceID="srcState"  
     DataTextField="StateName" DataValueField="StateName" Enabled="False" TabIndex="125"  
     runat="server" />  

      <asp:DropDownList ID="ddlTState" AppendDataBoundItems="True" DataSourceID="srcState"
          DataTextField="StateName" DataValueField="StateName" Enabled="False" TabIndex="125"
          runat="server" />

EditItemTemplate:

Code:

 <asp:DropDownList ID="ddlEState" AppendDataBoundItems="true" DataSourceID="srcState"  
     DataTextField="StateName" DataValueField="StateName" TabIndex="125" runat="server">  
     <asp:ListItem Text="--State--" Value="" />  

      <asp:DropDownList ID="ddlEState" AppendDataBoundItems="true" DataSourceID="srcState"
          DataTextField="StateName" DataValueField="StateName" TabIndex="125" runat="server">
          <asp:ListItem Text="--State--" Value="" />

Code:

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load  
     lsv = Util.FindChild(Me, "lsvProfile")  'Util.FindChild instead of FindControl
     'If Not IsPostBack Then  
     ddl = Util.FindChild(lsv, "ddlEState")  
     If ddl IsNot Nothing Then ddl.SelectedValue = Profile.State  
     ddl = Util.FindChild(lsv, "ddlTState")  
     If ddl IsNot Nothing Then ddl.SelectedValue = Profile.State  
     'End If  
 End Sub

Resolved with this code:

Code:

    Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
        lsv = Util.FindChild(Page, "lsvProfile")
        If Not IsPostBack Then
            Try
                lsv.EditIndex = 0
                rbl = Util.FindChild(lsv, "rblEGender")
                If rbl IsNot Nothing Then rbl.SelectedValue = Profile.Gender
                ddl = Util.FindChild(lsv, "ddlEState")
                If ddl IsNot Nothing Then ddl.SelectedValue = Profile.State
                ddl = Util.FindChild(lsv, "ddlEBirthDay")
                If ddl IsNot Nothing Then ddl.SelectedValue = Profile.BirthDay
                ddl = Util.FindChild(lsv, "ddlEBirthMo")
                If ddl IsNot Nothing Then ddl.SelectedValue = Profile.BirthMo
            Catch ex As Exception
            End Try
        End If
    End Sub

    Protected Sub lsvProfile_ItemDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.ListViewItemEventArgs) Handles lsvProfile.ItemDataBound
        ddl = Util.FindChild(Me, "ddlEState")
        If ddl IsNot Nothing Then ddl.SelectedValue = Profile.State
        ddl = Util.FindChild(Me, "ddlEBirthMo")
        If ddl IsNot Nothing Then ddl.SelectedValue = Profile.BirthMo
        ddl = Util.FindChild(Me, "ddlEBirthDay")
        If ddl IsNot Nothing Then ddl.SelectedValue = Profile.BirthDay
        rbl = Util.FindChild(Me, "rblEGender")
        If rbl IsNot Nothing Then rbl.SelectedValue = Profile.Gender

    End Sub
