Or, simpler and more efficient:

beforeSelectRow: myBeforeSelectRow

(ie there's no need to wrap your handler in an anonymous function)

thank's dvorak, this works better with the return statement.

This worked in my case in IE7/FF, etc.

Are you missing the return keyword in the beforeSelectRow() function?

beforeSelectRow: function(rowId, e) {
return myBeforeSelectRow(rowId,e);
}

Hello,

Is there something special to do for the "return true" to work ?

I had that first problem : http://www.trirand.com/blog/?p.....ut-fields/

Thank's to Mark, this is solved, except that in my case, the return true does not seem to execute default behaviour.

beforeSelectRow: function(rowId, e) {
myBeforeSelectRow(rowId,e);
}

//outside the grid : this should act as default handler

function myBeforeSelectRow(rowid, e) {
return true;
}

This code does not work for me, either on ie 6, nor firefox 3.x & jqgrid 3.6

Thank's for your help

Unfortunately, the exact way to do this varies depending on the callback, but for the beforeSelectRow, just return "true".

Thanks for the reply Tony. Sorry, I don't think I explained my problem right. So jqgrid has default event behavior for when the user selects a row for example. If I implement an event, like beforeSelectRow, then the default behavior does not happen. Only what's in my beforeSelectRow function will be run. I'm trying to find a way to have it do both. Execute jqgrid's default event behavior as well as my code.

beforeSelectRow: function(rowid) {

// do some custom code

// do jqgrid's default beforeSelectRow code

};

Hello,

For what I understand you can:

beforeSelectRow: function(rowid, e)

{

myfunction();

}

Outside the grid

function myfunction ()

{

// do something

}

And then you can call it where you want

There are many very useful extension points in the grid however I often find that I'd like the default behavior for an event to still take place, along with a bit of my code. So have it run the code in my function and then do what it normally would have done have I not provided this function.

For example, say I implement beforeSelectRow event:

beforeSelectRow: function(rowid) {

jQuery("#my_div").css({ "white-space" : "normal", "height" : "30px" });
},

Is there a way to then call the default beforeSelectRow() event handler in jqGrid? Something like base.beforeSelectRowI(rowid)?

I know this isn't exactly object oriented programming so, I'm wondering if there's a way to emulate this behavior. use jquery's trigger event functionality?
