grid events

I'm looking all over for an event to handle when a row is deleted from a grid and a row is no longer selected. I'd like to disable the delete button when this happens.

Any insight?

Thanks...

I thought I should mention that I am deleting the row from the data source and then repolling the XML and then updating the grid. Ultimately what I'd like to do is disable a button when nothing is selected in the grid.

Start with the grid events http://www.activewidgets.com/aw.ui.grid/

However, your description requires some logic handling. When you repoll, do you clear the button? Or do you look for a previously selected row?

Anthony,

Thanks for you responce. I've been to the link you provided, but the only clear event would be onRowDeleted. The way I read it, that only fires when deleteRow() is used. Since I am not deleting rows from the grid that doesnt sound like it will work for me.

I am using the onRowClicked to enable the button:grid.onRowClicked = function(event, rowIndex){
        if (this.getRowPosition(rowIndex) >= 0){
            document.getElementById('button').disabled = "";
        }
    }

And I am also modifying the default responce of the table so it should disable the button every time the table is reloaded:var defaultResponse = table.response;
    table.response = function(xml){
        defaultResponse.call(this, xml);

        document.getElementById('button').disabled = "disabled";
            
        if(table.getCount()<=0){
            document.getElementById('button').disabled = "disabled";
        }
    }

Unfortunately, its not working as planned.

Any more ideas?

Thanks again.

Er ... shouldn't you be doing -
...disabled = true
...disabled = false
instead?

Also if you use an AW button, which is a JavaScript object, you can use the object reference instead of searching for the object's ID via the document.
