In Grids, does not work function "focusRow" :(

[lbpf]

This my code:

var XmlExample = {
    init : function(){
        var schema = {
            tagName: 'item',
            id: 'uid',
            fields: ['id', 'name', 'producer']
        };
        this.dataModel = new YAHOO.ext.grid.XMLDataModel(schema);
        this.dataModel.onLoad.subscribe(this.onLoad.createDelegate(this));

        var myColumns = [
			{header: "ID", width: 21, sortable: true}, 
			{header: "Name;", width: 21, sortable: true}, 
			{header: "Prod", width: 20, sortable: true}
		];
		var colModel = new YAHOO.ext.grid.DefaultColumnModel(myColumns);
		var sm = new YAHOO.ext.grid.SingleSelectionModel(); 

        this.grid = new YAHOO.ext.grid.Grid('xml-grid-example', this.dataModel, colModel, sm);
	this.grid.addListener('rowdblclick', this.dblclick); 
        this.grid.render();
    },
    dblclick : function(grid, rowIndex){    
	var id = grid.getDataModel().getRowId(rowIndex); 
	grid.getView().focusRow(20);	
    },
    
    onLoad : function(){    

    },
    scroll : function(idRow){
	grid.getView().focusRow(20);	//  don't worked

    }, 
    search : function(mid, wfilter){
        getEl('load-ind').show();
        var params = {'mid': mid, 'wfilter': wfilter};
        this.dataModel.load('/catalog/getlist.php', params, this.clearIndicator);
    },
    
    clearIndicator : function(file){
        getEl('load-ind').hide();
    }
}
YAHOO.util.Event.on(window, 'load', XmlExample.init, XmlExample, true);

I have made function "Scroll" with parameter idRow and I wish it to cause after filling grids. But function don't work. How it correctly to make? And second question: How to find out number of the necessary line on entrance parameters from a server?

Thanks for the answers.

Have you tried grid.scrollTo(20)? That is the preferred way to scroll to a row and doesn't use focus.

You may end up with conflicting operations though because when a row is selected it is focused. You are trying to focus a different row at the same time. I'm not sure what the results would be.

Yes, I tried grid.scrollTo() - this work, but I need allocation of a line instead of is row scrolling to it. It is necessary for search.

[jack.slocum]

What do you mean allocation of line? Selecting the row? That's is done through the grid's selection model.

[lbpf]

And how then to selecting the row?

It's right there in the documentation at http://www.yui-ext.com/deploy/yui-ext/docs/

You need to get the SelectionModel from your grid, and ask that to do it.

Many thanks. Excuse, has badly read through the instruction.
