    <p>I have to create some form, in which users can create multiple tests for some data. If user want to validate data, he must check Checkbox in appropiate row and column for a test and then, click button titled "Validate tests". If user want to add new test (i.e. Test2), he must press "Add test" button.</p> <p>All data are stored into DataTable (dtTests) and displaying by GridView (dgvTests) on aspx page.</p> <p>My question is, how can i get checked-values for each checkboxes ?</p> <p><strong>Example website:</strong> In Example, user add two tests (look on image: <a href="http://i.stack.imgur.com/cR8l5.jpg" rel="nofollow">http://i.stack.imgur.com/cR8l5.jpg</a>). </p> <ul> <li>In Test1, he want to validate years: 1990, 1993, 1999 </li> <li>In Test2, he want to validate years: 1990, 1993, 1998, 1999</li> </ul> <p><strong>New Test column in dtTests:</strong></p> <pre><code>DataColumn dc = new DataColumn("Test" + i.ToString()) { DataType = typeof(Boolean), ReadOnly = false }; dtTests.Column.Add(dc); </code></pre> <p><strong>I add new TestX column to gridView in this way:</strong></p> <pre><code>TemplateField cbxTest = new TemplateField(); cbxTest.HeaderTemplate = new CheckBoxTemplate(DataControlRowType.Header, "Test" + i.ToString(), "Test" + i.ToString()); cbxTest.ItemTemplate = new CheckBoxTemplate(DataControlRowType.DataRow, "Test" + i.ToString(), "Test" + i.ToString()); dgvTests.Columns.Add(cbxTest); </code></pre> <p><strong>Here's class for CheckBoxTemplate:</strong></p> <pre><code>public class CheckBoxTemplate : ITemplate { private DataControlRowType templateType; private string columnName; private string bindName; public CheckBoxTemplate(DataControlRowType _type, string _colName, string _bindName) { templateType = _type; columnName = _colName; bindName = _bindName; } public void InstantiateIn(Control container) { switch (templateType) { case DataControlRowType.Header: Literal lc = new Literal() { Text = String.Format("&lt;b&gt;{0}&lt;/b&gt;", columnName) }; container.Controls.Add(lc); break; case DataControlRowType.DataRow: CheckBox cbx = new CheckBox(); cbx.DataBinding += new EventHandler(this.cbx_DataBinding); container.Controls.Add(cbx); break; default: break; } } private void cbx_DataBinding(Object sender, EventArgs e) { CheckBox cbx = (CheckBox)sender; GridViewRow row = (GridViewRow)cbx.NamingContainer; cbx.Checked = Convert.ToBoolean(DataBinder.Eval(row.DataItem, bindName).ToString()); } } </code></pre>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
