Clientside functions don´t work

[Elmar]

Hi there.

I have some issues with clientside scripting of the combobox. All the getters and setters don´t work.

Definition:
var combo_route = $get('<%= DropDown_Routes.ClientID %>');
combo_route.set_text(title);

Produces an "is not a function error" (it is not undefined! "ctl00_navisub_DropDown_Routes"). Am I missing something here?

Best regards,
Elamr

Hello Elmar,

I suggest that you try to get the instance of RadComboBox, like:
var combo_route = $find('<%= DropDown_Routes.ClientID %>');

Hope this helps.

Unfortunately that does not work either.
I think this behavior might be because I am accessing this thing from an external script that is loaded via "script src".

So what I am doing in the page itself is, is to look for the clientid of that control:
var dropdown_routes = $get('<%= DropDown_Routes.ClientID %>');

That works just fine but I can´t access all the telerik custom clientside methods from the external script although the variable itself is declared and filled.

How do I integrate the clientside functions in external scripts? My guess is that this is what 90% of developers use frequently.

Do you have this in a user control, ascx file? I fought this for days, and some of the items in the help are not the correct syntax either. I am posting a couple of examples below that I hope will help.

Jeff

function

OnClientSelectedIndexChangingDDL(sender, eventArgs)
{
var combo = sender;
var name = combo.get_id();
alert(name);
....

......
clearddl("Usercontrol1_RadComboBox1");
.......

function

clearddl(objSelect)
{
var combo = $find(objSelect);
combo.get_items().clear();
combo.set_text("");
}

function

OnClientItemsRequestingDDLFascia(sender, eventArgs)
{
var context = eventArgs.get_context();
context["RuleSet"] = "DDLFascia";
context["param1"] = document.getElementById("Usercontrol1_RadComboBox1_Input").value;
}

Hi there. I actually ended up removing the component because it was too unstable for production use. The async data retrieval worked most of the time but sometimes it would fire an async error. Although this error can be caught and suppressed, it is not a good thing to have unpredictable errors in my app.

Thanks for providing this support anyway!
