Hi.

I created and populated WebCombo dynamically on a Server Side (and added it to the table).

This is a main declaration:

Dim wcbo = New WebCombo

------ more coding-------

-------and finally:--------

wcbo.PopulateUnboundData(....)

Everything works fine. Now I need to code for a ClientSideEvent, for example OnAfterItemSelected.

I need to pass parameters to a JavaScript function and have a problem doing that.

I tried two methods:

wcbo.LayoutSettings.ClientSideEvents.OnAfterItemSelected = "MyFunction(document.all.wcbo);" - parameter is passed as an Input instead of a WebCombo and it doesn't work

and

wcbo.Attributes.Add("OnAfterItemSelected", "MyFunction(document.all.wcbo);" - I don't get any errors, but Attributes.Add seems to not working for WebCombo at all. I cannot even make work a simple function like "alert('Test');".

Unfortunately, knowledge base id down. Does anyone know how to call JavaScript function from the Server Side?

Thank you.

Hi,

Yes you can. Please try the snippet below based on your given code.

wcbo.LayoutSettings.ClientSideEvents.OnAfterItemSelected = "MyFunction";

You can only type the method's name not with the paramaters.

Hope this helps.

Regards,

Niven

Niven,

Thanks for the replying. The problem is I need to pass a WebCombo (wcbo) as a parameter. Otherwise,

I cannot take any actions with this control in JavaScrtiptj, since this WebCombo is created dynamically on the .aspx.vb page and doesn't exist in the .aspx page.

Thanks,

Ellen

Hello,

Please look into my attached simple sample of your scenario. You can do whatever you want with your function. It will automatically pass a parameter.

Hope this helps.

Niven
