[CLOSED] Page PostBack Query

[vijay.sahu]

Hi Danil,


How Do I stop Page from getting PostBack whenever I use DirectEvent or DirectMethod. Please show some Example on this .

[Daniil]

Hi @vijay.sahu,

Returning false from a DirectEvent's Before handler stops a request.

Example 1

<ext:Button runat="server" Text="Test">
    <DirectEvents>
        <Click OnEvent="TestDirectEventHandler" Before="return true || false;" />
    </DirectEvents>
</ext:Button>

Returning false from the same Listener also stops a request.

Example 2

<ext:Button runat="server" Text="Test">
    <Listeners>
        <Click Handler="return false;" />
    </Listeners>
    <DirectEvents>
        <Click OnEvent="TestDirectEventHandler" />
    </DirectEvents>
</ext:Button>

Hi Danil,

I think the question posted initially was not clear enough.
When we give a call to a Direct Method or a DirectEvent, it goes to Page_Load Event and there we check if the Page is PostBack or an AjaxRequest call or not by using IsPostBack or X.IsAjaxRequest properties.

What I actually want is while firing any one of the above methods, it should not go to the Page_Load but instead it should directly go the Method or Event stated in the Page.


Current behaviour
Initial Load : page_load
Click of a button having direct event/method : Page_Load -> DirectEvent/Method

What I actually want is
Initial Load : page_load
Click of a button having direct event/method : DirectEvent/Method (It should directly go to that method rather than to have a call in page_load)



Pls Provide your Inputs with sample code

[Daniil]

A static DirectMethod allows to achieve your requirement, see #4 here:

Please note that no Page lifecycle means no controls, i.e. you won't get an access to any controls.

Thank You Danil.

Eventually I got my solution to use static method or try for an ajax call.

Thank You Danil
