Solution 1

Try writing your filter this way:

C#

bs.Filter=String.Format("Id LIKE '%{0}%'", txtsearchId.Text):

(added '% %'). if this doesn't work:

The MSDN Documentation https://msdn.microsoft.com/en-us/library/system.windows.forms.bindingsource.filter(VS.90).aspx[^] says:

Only underlying lists that implement the IBindingListView interface support filtering.

so maybe it's a problem with your datasource ?
