Postback only on checkbox and not on +-

Hi,

I have a tree built from a hierarchical database table, and each node in my tree has a corresponding checkbox. In Mozilla, the tree works fine but in IE a very annoying "blinking" effect is caused by the page reloading on postback. To get around this, I want the tree only to postback when I check a checkbox (because I do some server side code then to automatically check the parent nodes of the selected item all the way up to the top of the tree) and not to postback on expand / collapse.

Anyone know how?

Thanks in advance.

Open the treeview.htc file and change the Javascript.
On the function "function nodePlusMinusClick()" comment the lines
"if (doNodePlusMinusClick(el) == true)
fireQueuedEvents();"

Thanks Kabindas.

Just one small note for other readers who might find this useful: commenting both lines will mean you can't expand or collapse the nodes, so I simply commented out the fireQueuedEvents call ( not forgetting to add { } to the if statement, of course ).

Thanks for this tip.Unfortunatly,for some reason is not working for me.

I have..............



function nodePlusMinusClick()


{


    if (g_bInteractive == false)


        return;





    var el = this.parentElement.treenode;


    if (doNodePlusMinusClick(el) == true)


	{


        //fireQueuedEvents();


	 return;


	}


}

I am I wrong?

I got it thank you..

TIP

If you do not want to post back when a user clicks the node text

comment the 'fireQueuedEvents();' as I shown below

function nodeClick()
{
if (g_bInteractive == false)
return;

var el = this.parentElement.treenode;
if (doNodeClick(el) == true)
{
if (element.getAttribute("selectExpands") == true)
doNodePlusMinusClick(el);
//fireQueuedEvents();
}
}
