Hi,

I have an eo:ListBox as a DropDownTemplate item.

The listbox has an ASP:Table as an ItemTemplate which I would like to populate dynamically.

Problem is after postbacks the table does not retain the data in the rows and displays the same number of data rows without the data.

I hope this is not a trivial question, as I have tried to resolve it endlessly.

Thank you in advance for your advice on hos to resolve this issue.

Below is the code:

<eo:ComboBox ID="ComboBox2" runat="server" Width="675px" ControlSkinID="None"
DefaultIcon="00101070" HintText="" AllowCustomText="False"
AutoPostBack="True" Height="25px">
<IconAreaStyle CssText="font-family: tahoma; font-size: 11px; background-image:url(00107007); background-position: left left; background-repeat:no-repeat; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<DropDownTemplate>
<asp:SqlDataSource ID="SqlDataSource2" runat="server"
ConnectionString="<%$ ConnectionStrings:crap %>"
SelectCommand="....">
</asp:SqlDataSource>
<eo:ListBox ID="ListBox1" runat="server" ControlSkinID="None"
DataTextField="Resource" DataValueField="ResourceID"
DataSourceID="SqlDataSource2" Height="200px"
Width="670px">
<FooterStyle CssText="background-image:url('00106002'); background-position: left top; background-repeat: repeat; height:16px;padding-bottom:2px;padding-left:7px;padding-right:2px;padding-top:2px; margin-top:3px; height: 18px;" />
<BodyStyle CssText="border: solid 1px #dedede;" />
<ItemListStyle CssText="padding: 4px;" />
<DisabledItemStyle CssText="border-bottom: solid 1px #dedede; color: #c0c0c0; padding: 2px; padding-left:2px; padding-top:4px;padding-right:2px;padding-bottom:4px;" />
<ItemStyle CssText="border-bottom: solid 1px #dedede; padding-left: 2px; padding-right:2px; padding-top:4px; padding-bottom: 3px; background-color:white;" />
<ListBoxStyle CssText="font-family: Tahoma; font-size:12px;background-color:white;" />
<FooterTemplate>

</FooterTemplate>
<MoreItemsMessageStyle CssText="padding:2px;" />
<HeaderStyle CssText="background-image:url('00106001');background-position-x:left;background-position-y:top;background-repeat:repeat;height:16px;padding-bottom:2px;padding-left:7px;padding-right:2px;padding-top:6px;height:19px;margin-bottom:3px;" />
<HeaderTemplate>

</HeaderTemplate>
<SelectedItemStyle CssText="background-color: #08246b; color:white; padding-left:2px; padding-top:4px;padding-right:2px;padding-bottom:4px;" />
<ItemHoverStyle CssText="border-bottom: solid 1px #dedede; padding-left: 2px; padding-right:2px; padding-top:4px; padding-bottom: 3px; background-color:#f3f7fc;" />
<ItemTemplate>
<%#Eval("ResourceID")%><br />

<asp:Table ID="Table1" runat="server">
</asp:Table>
</ItemTemplate>

</eo:ListBox>
</DropDownTemplate>
<TextStyle CssText="font-family: tahoma; font-size: 11px;" />
<TextAreaStyle CssText="font-family: tahoma; font-size: 11px; border-top: solid 1px #3d7bad; border-bottom: solid 1px #b7d9ed; vertical-align:middle;padding-left:2px; padding-right:2px;" />
<ButtonStyle CssText="width:17px;height:23px;" />
<ButtonAreaStyle CssText="background-image:url(00107005);" />
<IconStyle CssText="width:16px;height:16px; display: none;" />
<ButtonAreaHoverStyle CssText="background-image:url(00107006);" />
<HintTextStyle CssText="font-style:italic;background-color:#c0c0c0;color:white;line-height:15px;" />
</eo:ComboBox>



Protected Sub ListBox1_ItemDataBound(ByVal A_0 As Object, ByVal A_1 As EO.Web.ListItemEventArgs) Handles ListBox1.ItemDataBound

If Not IsPostBack Then
Dim iRow As TableRow
Dim oCell As TableCell

If A_1.Item.ItemType = ListItemType.Item Then
Dim lst As EO.Web.ListBoxItem = A_1.Item
Dim tbl As Table = CType(lst.Container.FindControl("Table1"), Table)

With tbl
oCell = New TableCell
iRow = New TableRow
oCell.Text = "John"
iRow.Cells.Add(oCell)

oCell = New TableCell
oCell.Text = "Wiley"
iRow.Cells.Add(oCell)

oCell = New TableCell
oCell.Text = "Winston"
iRow.Cells.Add(oCell)

.Rows.Add(iRow)

oCell = New TableCell
iRow = New TableRow

oCell.Text = "Duncan"
iRow.Cells.Add(oCell)

oCell = New TableCell
oCell.Text = "Maina"
iRow.Cells.Add(oCell)

oCell = New TableCell
oCell.Text = "Otlhe"
iRow.Cells.Add(oCell)

.Rows.Add(iRow)

End With
End If

End If
End Sub

'**Note I also tried with the page load method

Hi,

You can try to call DataBind explicitly and see if it works. It will be something like this:

Code: C# 
//Get the ListBox object inside the DropDownTemplate
ListBox = DirectCast (ComboBox1.DropDownContainer.FindControl("ListBox1"), ListBox)

//DataBind ListBox
ListBox.DataBind()


Please let us know if it works for you.

Thanks!
