If your "Method to Execute" on the ListView is set to the BO fill method as I outlined above (FillByTextBoxValue(string pTextBoxValue)), then all you need in the ListPopulating event is the following:

On the leave focus event of the textbox (or whereever you need it), all you have to do is:

since the method to populate the BO could not be FillByParent. Can you post an screenshot of the List View Population Settings, I would like to see what you have in the Method to Execute. 

Here is an example of what I use in one of my forms:

In this case I use the CopyDataFrom(BusinesLayerBase,BusinessCloneDataType) because I have an instance of the bizBuildings BO in the form and I simply update that BO instance and the listview will copy all records to the ListView internal BO.  I find this method easier to maintain.

P.S

I'll be online for a couple of hours in case you want to pursue with this issue.

The error is first post this topic

http://forum.strataframe.net/Topic18700-6-1.aspx

Ok, even though I use VB your code looks good, all you have to do now is just requery the ListView control in one of the places mentioned by Bill, in the Textbox control or in the Page's Activate.

Are you getting any specific error? or just the listview is not being populated?

Edhy Rijo

no

So it is now working for you?

For population in Load Form, i configured populationDataSourceSetings and implemnt this code:

        private void lvPedidoCompraItem_ListPopulating(ListPopulatingEventArgs e)
        {
            e.Parameters[0].Value = this.sysPedidoCompraItemBO1;
            e.Parameters[1].Value = MicroFour.StrataFrame.Business.BusinessCloneDataType.ClearAndFillFromDefaultView;
        }
        private void lvPedidoCompraItem_RowPopulating(RowPopulatingEventArgs e)
        {
            //-- Establish Locals
            sysPedidoCompraItemBO loBO = ((sysPedidoCompraItemBO)e.BusinessObject);
            //-- Set the not count
            //e.Values[1].DisplayValue = CustomerNotes.GetNoteCount(loBO.cust_pk).ToString("n0");
        }

But i use   

e.Parameters[0].Value = for_cod.Text;

and delete

sysPedidoCompraItemBO loBO = ((sysPedidoCompraItemBO)e.BusinessObject);

, when initialize form with error.

You could pass the parameter in the Requery method of the ListView:

MyListView.Requery(myCoolParameter);

But, as I found out over time, it is better to pass the parameter in the ListPopulating event of the ListView (from docs using VB):

Then, whenever you need to refresh the ListView control, it is a simple call to its Requery method:

MyListView.Requery();

No need to remember to pass a parameter since it is handled in the event.  Good stuff.  A "set it and forget it" type of approach.

Whoa.

Thanks!

Wow, never noticed that! That's cool!



Thanks for asking Bill...I've often done the quoting thing myself. The last 10 posts is much better. I also noticed that you can also open the complete topic in a new window...even better for those lonnnnng posts.
