    [CLOSED] Change panel width from Javascript

    Hi,
    I would like to change panel width size from javascript.
    Here my code but don't work:

    Javascript code:

    <script type="text/javascript">
        var ExtraExpandMAP = function (pannello) {
            pannello.setWidth = 920;
        };
    </script>

    Asp.Net code:

    <ext:Panel ID="PanelLazyMAP" runat="server" 
    	Region="East" 
    	Width="460"                 
    	Title="Mappa"
    	Layout="Fit" 
    	Floatable="false"
    	Resizable="true"
    	Collapsed="true"                    
    	Collapsible="true"
    	AutoScroll="false"
    	BodyStyle="background-color:#ffffff;"
    	MarginSpec="84 0 0 0" AnimCollapse ="false">
    	<HeaderConfig>
    		<Items>
    			<ext:Button ID="btnExpandExtraMAP" runat="server" Icon="RewindGreen">
    				<Listeners>
    					<Click Handler="ExtraExpandMAP(#{PanelLazyMAP});">				
    					</Click>
    				</Listeners>
    			</ext:Button>
    		</Items>
    	</HeaderConfig>
    </ext:Panel>
    Does anyone have any idea?
    Thank you!

    Ops I apologize for the trouble.... I found the error in my code:

    instead of:
    pannello.setWidth = 920;
    coding:

    pannello.setWidth(920);

    For information, not working also:

    pannello.width = 920;
    You can mark as closed!

    Hello! Thanks for sharing the outcome!

    For instance, panello.width = 920 actually works. But here, you are actually setting the width of the panel next time it is rendered on the screen. That's why you see no results with this. Should be set when defining the panel (in Page_Load() time, for example).

    So using the method setWidth(920) does not only set the width property, but also runs needed code to apply the settings on the fly.
