Filter BindingSource when DataSource is a BindingList

Question

I have read from a excel sheet and wrote this for a BindingList, in Form_Load this is set to a DataSource as BindingSource:

bd = new BindingSource(); //insta         


        

Answer 1

You can not use Filter property to filter a BindingSource which it's DataSource is set to a BindingList<T>.

Only underlying lists that implement the IBindingListView interface support filtering.

You can filter the BindingList<T> using Linq:

var filteredBindingList= new BindingList<T>(bindingList.Where(x=>some criteria).ToList());

Then you can use filtered binding list as data source.

Answer 2

You may try it:

    bd.resetBindings(false)

Good luck

UPDATE

I would try something like this:

    bd.Filter = string.Format("TAG_FAZENDA like '%{0}%'", cbTagFaz.Text);
    gvFiltro.resetbindings(false)
    gvFiltro.Update();

    bindNav.resetbindings(false)
    bindNav.Update();

Just this.
