Want to fire Dropdown SelectedIndexChanged Event in Javascript
Solution 1
Here is a working example:
function fireEvent(element,event){
if(document.createEvent){
// dispatch for firefox + others
var evt = document.createEvent(”HTMLEvents”);
evt.initEvent(event, true, true ); // event type,bubbling,cancelable
return !element.dispatchEvent(evt);
}
else{
// dispatch for IE
var evt = document.createEventObject();
return element.fireEvent(’on’+event,evt)
}
}
Solution 2
Call onchange method like that at client side :
document.getElementById('yourDropdownsClientId').onchange();
EDIT : If you set your dropdown's AutoPostBack property to true, the code above will post your page to server, than your server side event will be called.
But If you want to call your event manually, you can all it anywhere in your page's codebehind like that :
myDropDownList_SelectedIndexChanged(null, new EventArgs());
