I'm not overly familiar with winforms and the correct way to filter data on a datagrid view. But something like the following may help you.

var filteredItems = Items.Where(row=>textbox1.Lines.Contains(row.FilterColumn));

you may want to do something more to allow for ignoring the case of what you are filtering on, but filteredItems should be a step towards what you want.

With what exactly? Where will the filtering take place, on the server or on the client-machine? And how do your lines in the textbox match up with the tablenames? Perhaps if you showed us some code that explains how you load the data in there, we might hint what the most appropriate solution could be.

Let's assume your DataGridView is already full of Data, in Cells, organized in Rows and Columns, naturally. Now for each line of text in the multi-line TextBox: Exactly how do you want to use that to filter either certain Cells, or certain Rows, or certain Columns, in your DataGridView ? What exactly does "filter" mean here: to hide something that does not "match," or ... ? What have you tried so far ? I do think if you can write up your problem more clearly, that it would be better, for you, if you posted it in the QA section. best, Bill

Thanks everybody for helping! And sorry for late answer. Bill , as you're saying i have a datagridview full of data. What I want is show the datagridview rows that match with the lines in the multiline textbox For example: my datagridview have two columns: Name and Last Name to say something... In the textbox I type in the first line John and in the second line I type Mary. I want the datagrid to show me only the rows that have these names. And if I keep typing in others lines keep doing the firter or search... I hope I explained better now... Thanks in advance!

If you will re-post this in QA, with the details you've disclosed: I will respond in greater depth, and I think you'll get many other helpful comments from other people. best, Bill
