No that didn't work either

The selectedIndex just isn't being persisted on postback

Hi Neill,

To add selected WebListBoxItem to another WebListBoxItem, I suggest you to use SelectedIndex property in WebListBox. SelectedIndex is also usefull because you don't have to do looping to find a selected items. You can change your code behind into codes bellow :

 protected void btnAddItem_Click(object sender, EventArgs e)
 { 
    int i = WebListBox1.SelectedIndex;
    WebListBoxItem wli = new WebListBoxItem();
    wli.Name = WebListBox1.Items[i].Name;
    wli.Text = WebListBox1.Items.GetNamedItem(wli.Name).Text;
    WebListBox2.Items.Add(wli);
 }

Please let me know whether it is work as your expectation or not ?

Hope this helps.

I'm trying to get the selected item of a WebListBox on post back so i can add one item in a weblistbox to another WebListBox but the selected item isn't being detected selected when the button is clicked

Code below

<td>

<ISWebEssentials:WebListBox ID="WebListBox1" runat="server" Height="160px"

Width="250px" >

<Items>

<ISWebEssentials:WebListBoxItem Name="WebListBoxItem0" Text="1" />

<ISWebEssentials:WebListBoxItem Name="WebListBoxItem1" Text="2" />

<ISWebEssentials:WebListBoxItem Name="WebListBoxItem2" Text="3" />

<ISWebEssentials:WebListBoxItem Name="WebListBoxItem3" Text="4" ToolTip="4" />

</Items>

</ItemStyle>

</ISWebEssentials:WebListBox></td>

<asp:Button ID="Button1" runat="server" Text="Add" ToolTip="Add item" onclick="btnAddItem_Click" /><br /><br />

</td>

<td>

<ISWebEssentials:WebListBox ID="WebListBox2" runat="server" Height="160px" Width="250px">

<Items>

<ISWebEssentials:WebListBoxItem Name="WebListBoxItem0" Text="a" />

</Items>

</ISWebEssentials:WebListBox></td>

</tr>

</table>

Code behind

protected void btnAddItem_Click(object sender, EventArgs e)

{

foreach (WebListBoxItem wli in WebListBox1.Items)

{

if (wli.Selected)

{

WebListBox2.Items.Add(wli);

}
