Problme with the listbox client side SelectedIndexChanged event

[santhosh]

Hi,

I am using radlistbox and I want to perform some operations on listbox client side SelectedIndexChanged event and below is my code.

 

<script language="javascript" type="text/javascript">

 

 

function onSelectedIndexChanged(sender, args)

 

{

alert(

"Selected index changed");

 

}

 

</script>

 

 

<table cellpadding="2" cellspacing="2" border="0" class="TableBorder" width="100%">

 

 

<tr valign="top">

 

 

<td style="width: 105px">

 

 

&nbsp;</td>

 

 

<td class="clsLabel">

 

 

<asp:Label id="lblExisting" runat="server" text="<%$ Resources:pageLabels, lblExistingPlans %>" CssClass="clsLabel"></asp:Label>

 

 

</td>

 

 

<td style="width: 100px">&nbsp;</td>

 

 

</tr>

 

 

<tr valign="top">

 

 

<td style="width: 105px">&nbsp;</td>

 

 

<td>

 

 

<telerik:RadListBox ID="lstExistingPlans" runat="server" Width="763px" Height="250px" CssClass="clsLable" Skin="Office2007" OnClientSelectedIndexChanged="onSelectedIndexChanged()"></telerik:RadListBox>

 

 

</td>

 

 

<td style="width: 100px">&nbsp;</td>

 

 

</tr>

 

 

<tr valign="top">

 

 

<td style="width: 105px">&nbsp;</td>

 

 

<td class="clsLabel">

 

 

<asp:Label id="lblAvailable" runat="server" text="<%$ Resources:pageLabels, lblAvailablePlans %>" CssClass="clsLabel"></asp:Label>

 

 

</td>

 

 

<td style="width: 100px">&nbsp;</td>

 

 

</tr>

 

 

<tr valign="top">

 

 

<td style="width: 105px">&nbsp;</td>

 

 

<td>

 

 

<telerik:RadListBox ID="lstAvailablePlans" runat="server" Width="763px" Height="250px" CssClass="clsLable" Skin="Office2007" AutoPostBack="true"></telerik:RadListBox>

 

 

</td>

 

 

<td style="width: 100px">&nbsp;</td>

 

 

</tr>

 

 

</table>

Now the problem is this client side event fires on each postback but when I click on the listbox on which i have written the client side event its not working instead its throwing a javascript error as.

"Error: a[b] is not a function

Hi santhosh,

Please subscribe to the client event without using the parenthesis:

OnClientSelectedIndexChanged="onSelectedIndexChanged"
