    <p>I have a list of objects. My classes looks like this:</p> <pre><code> class Line { public string A { get; set; } public object B { get; set; } public string C { get; set; } } class More_B { public Information Information { get { return _Information; }} public Description Description { get { return _Description ; }} private Information _Information = new Information(); private Description _Description = new Description (); } class Information { public string Name { get; set;} public string Type { get; set;} public string Further_Info { get; set;} } </code></pre> <p>In my main class at the end I get all data inside <code>Line</code> class like this.</p> <pre><code>More_B info = new More_B(); Line main = new Line(); main.A = "Information about device"; main.B = info; main.C = "Some more information could be display here"; list3.Add(main); </code></pre> <p>So at the end I get list inside which I have all 3 fields <code>A</code> <code>B</code> <code>C</code>. I have my string values in <code>A</code> and <code>C</code> and in <code>B</code> when I check in debug mode I have Information object and inside of it I have all fields like <code>Name</code> <code>Type</code> and <code>Further_Info</code>.</p> <p>I later want to filter this column based on these values "Name" "Type" and "Further_Info", I tried it this way but it is not working. (I binded my list to DataView to be able to use RowFilter).</p> <pre><code>view2.RowFilter = "Line like '%" + textBox2.Text + "%'"; </code></pre> <p>How can I do it right?</p> <p>I am new to C#, so please forgive me, if I did something wrong. If something is hard to understand, let me know and I will try to post more of my code explaining what I did.</p> <p>EDIT: When I use this statement <code>view2.RowFilter = "Line like '%" + textBox2.Text + "%'";</code> I get error <code>Cannot perform 'Like' operation on read_display.More_B and System.String.</code></p> <p>EDIT2: I have 2 more methods for creating datatable for my class and then I do it like this: <code>DataTable ListAsDataTable2 = BuildDataTable2&lt;Line&gt;(list3); DataView ListAsDataView2 = ListAsDataTable2.DefaultView; this.dataGridView4.DataSource = view2 = ListAsDataView2;</code></p>

    2. COview2 is object of my DataView. I did it this way to be able to use RowFilter. It was not working without binding this data to DataView.

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
