Dear Syncfusion!

I want to call my EJDropDownList Change event from C# codebehind. 
This event what I want to call:

protected void EJDropDownList_Change(object sender, Syncfusion.JavaScript.Web.DropdownListEventArgs e) {

EJDropDownList_Change(sender, e); not work with this error:

cannot convert from 'System.EventArgs' to 'SyncFusion.JavaScript.Web.DropDownlistEventArgs'.

Hi Imre, 

Thank you for using Syncfusion products. 

To call the EJDropDownList Change event from codebehind, you need to define the DropdownListEventArgs and then you can pass it as parameter by setting its value to null. Kindly refer the following code snippet. 

Syncfusion.JavaScript.Web.DropdownListEventArgs args = null; 
EJDropDownList_Change(sender, args); 

We have prepared a sample, kindly refer to the following link for the sample: http://www.syncfusion.com/downloads/support/forum/131663/ze/DdlAspSample-933213496
