How to Focus inthe First Cell of a Newly-Added Row

问题:

I am adding a new blank row to a dojox.grid.DataGrid, and want to focus in the first cell of the new row.

I add the row by calling:

var new_row = {},  
attributes = store.getAttributes( items[0] );

dojo.forEach( attributes, function( attribute )
{                   
    dojo.forEach( attributes, function( attribute )
    {
        new_row[ attribute ] = null;
    } );

} );

store.newItem( new_row );

I believe the following code will do the focusing:

grid.focus.setFocusIndex( row_index, 0 );
grid.edit.setEditCell( grid.focus.cell, row_index );

But I cannot figure out how to only call this code after the grid has re-rendered. I guess I need to connect to an event. However, I can't see a likely event to use. onNew() seems to be called before the new row is added.

Here's a JSFiddle which gets as close as I can to a solution. http://jsfiddle.net/xDUpp/ (comment out the line marked edit and it adds the new row)

Thanks

Which version of Dojo are you interested in?

The Dojo API differs between ver. in this matter.

Look at: http://jsfiddle.net/keemor/xDUpp/11/

After store is modified grid needs a little time to rebuild itself, so setFocusIndex & setEditCell must also be delayed to work:

store.onNew = function( new_item ) {
    var rowIndex = new_item._0;                    
    window.setTimeout(function() {
        grid.focus.setFocusIndex( rowIndex, 0 );
        grid.edit.setEditCell( grid.focus.cell, rowIndex );
    },10);    

};
