Combining a server-side control with a client-side control!

Hi all,

I am trying to combine a server-side control with a client-side control.

I have created a listbox in both sides, the client-side control's code is:

<select size="4" name="lstFruit" id="Select1" ondblclick="lst_dblClick" visible="false">

<option value="Banana">Banana</option>

<option value="Apple">Apple</option>

<option value="Mango">Mango</option>

<option value="Orange">Orange</option>

</select> 

The other one is the server-side control which has this code:

I wanted to add the ondblClick attribute to the server-side control and i used this code in the page load to do it: lstITems is the server-side control i have created which hasn't the dblClick attribute

Me.lstITems.Attributes.Add("OndblClick", "lst_dblClick")

I made sure that the attribute has been added to the server-side control, but its not calling the required method which is:

<script runat="server" >

Protected Sub lst_dblClick(ByVal sender As Object, ByVal e As System.EventArgs)

lblResult.Text = "You double clicked this item!"

End Sub

</script>

Whenever i double click the item in the listbox i got error in page!

any idea how to solve this problem?

The only events available for a ListBox AFAIK are:

   Server-side:

      SelectedIndexChanged

   Client-side:

      onblur

      onchange

      onfocus

Also, the way that you're attaching the event:

     Me.lstITems.Attributes.Add("OndblClick", "lst_dblClick") 

makes it a client-side event and that's why you're getting the script error.

The proper way to attach a server-side event is:

     Protected Sub lst_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles lst.SelectedIndexChanged

Or

     AddHandler lst.SelectedIndexChanged, AddressOf lst_SelectedIndexChanged
