Hi,

Thanks for the reply. It seems a little strange that you are allowed to set the ID property, but then it gets overwritten internally.

My issue is that I sometimes need to select a specific item in the grid from another pane in thw window. I have access to the ID of the item which I would like to give to the individual items in the grid, but not the index of the item I want to select. I therefore would like to (in JavaScript) be able to locate the row in the grid by my ID (which happens to be a database GUID) and select it. I had planned to do this by assigning each row in the grid my specific ID, but now I cannot do this because of this restriction within the grid.

The only workaround I can think of is to manually add an attribute to each row of the grid in the ItemDataBound event as follows:

    
            e.Item.Attributes["rowid"] = "MyID";

However, this means that in the JavaScript I have to loop through every item in the grid trying to find my item and select it, which is very inefficient:

    
            var rows = $find( "Grid" ).get_masterTableView().get_element().rows;  
        
            for( var i = 0; i < rows.length; i++ )  
        
            {  
        
                if( rows[ i ].rowid == rowID )  
        
                {  
        
                    row = GetGridTable().get_dataItems()[i].get_element();  
        
                    break;  
        
                }  
        
            }
