Hi All, Some of the ASP.NET server controls (.NET 2.0) like DropDownList control, LinkButton etc., has postback property. When User clicks or selects these controls, a Postback will occur. Let us consider LinkButton control, which is extension of the HyperLink control. By using JavaScript, it provides us to execute some server side code, when user clicks on the LinkButton. Many web developers(especially developing Web applications for BlackBerry Web Browser) had come across situations like, LinkButton, DropDownList etc., is not working in BlackBerry web Browser.

To overcome this situation there is small work around for this. The below code matches the browser name from the Request object and set the ECMA(JavaScript) script version to 1.5, so that the BlackBerry Browser recognizes the javascript generated by the ASP.NET isapi filter.
Add the following code under <System.web> section:

<System.web>
    <browserCaps>        
        <filter>          
            <case match="(?i)BlackBerry">EcmaScriptVersion=1.5
        </filter>
    </browserCaps>
</System.web>

NOTE: Though <browserCaps> section is deprecated in .NET 2.0, still you can use this.
