    <p>I have a method where I am creating some image buttons. I added below line: btnCity.Click += new ImageClickEventHandler(btnCity_Click); to the method to code the click event.</p> <p>On @Jacek's request adding code where buttons are added:</p> <pre><code>private void LocateCities() { IDBManager dbManager = new DBManager(DataProvider.SqlServer); dbManager.ConnectionString = @"Data Source=server; Initial Catalog=db; Integrated Security = SSPI;"; try { dbManager.Open(); dbManager.CreateParameters(2); dbManager.AddParameters(0, "@Function", "All"); dbManager.AddParameters(1, "@Team", "All"); DataSet ds = new DataSet("Stuff"); ds = dbManager.ExecuteDataSet(CommandType.StoredProcedure, "sp_select_staff_and_cities"); foreach (DataRow dr in ds.Tables[0].Rows) { int xaxis = Convert.ToInt32(dr["xaxis"]) ; int yaxis = Convert.ToInt32(dr["yaxis"]) ; int textxaxis = xaxis + 30; int textyaxis = yaxis - 10; ImageButton btnCity = new ImageButton(); btnCity.ImageUrl = "~/Images/cyanball1.gif"; btnCity.Height = 10; btnCity.Attributes.Add("style", "Z-INDEX:100; POSITION:relative; left:" + xaxis + "px; TOP:" + yaxis + "px; Left:10px;Right:10px"); Label lblCity = new Label(); lblCity.Text = dr["city"].ToString(); lblCity.Attributes.Add("style", "Z-INDEX: 100;POSITION:relative; left:" + textxaxis + "px; TOP:" + textyaxis + "px"); PanelMap.Controls.Add(lblCity); PanelMap.Controls.Add(btnCity); } } catch (Exception ex) { Response.Write(ex.ToString()); } finally { dbManager.Dispose(); } } </code></pre> <p>I also created below method to handle click event:</p> <pre><code> void btnCity_Click(object sender, ImageClickEventArgs e) { ImageButton btnCity = (ImageButton)sender; Response.Write("works"); } </code></pre> <p>but it doesn't work. Any suggestions how it should look like?</p>

    2. COAlways clarify, "It doesn't work." What didn't work? Did you get an error, did you get a different output than what was expected, if so, what was the specific difference, etc. Also, in this case be sure to explain how you've observed what is/isn't working; it's possible you observed behavior improperly even though it was working.

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.

SQuiL has stopped working due to an internal error.

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