Here is some code for an interface I am trying to make. I am having serious problems understanding how events work. I have tried a lot of things, but they haven't worked. Any help is greatly appreciated... Basically, I am trying to develop an interface where I can get and select the various drives on a machine. The table is created, the buttons and links are created properly. However, when I click on the buttons or links, nothing happens, except that I see an error in Explorer's message bar saying "Error on Page". What am I doing wrong? public class WebForm1 : System.Web.UI.Page { protected System.Web.UI.WebControls.Label Label1; public System.Web.UI.WebControls.Table tblDrives; public event ImageClickEventHandler Click; private void Page_Load(object sender, System.EventArgs e) { displayDrives (); } public void addRows (string strDrive) //Used to add rows to the table { TableRow row = new TableRow (); TableCell celImg = new TableCell (); TableCell celText = new TableCell (); System.Web.UI.WebControls.ImageButton ibnDrive = new ImageButton (); System.Web.UI.WebControls.LinkButton lbnDrive = new LinkButton (); ibnDrive.ID = "ibn" + strDrive; lbnDrive.ID = "lbn" + strDrive; ibnDrive.ImageUrl = "http://localhost/BrowseTester/images/drive.gif"; lbnDrive.Text = strDrive; ibnDrive.CommandName = "ID"; ibnDrive.CommandArgument = strDrive; ibnDrive.Click += new ImageClickEventHandler (this.ImageButton_Click); celImg.Controls.Add (ibnDrive); celText.Controls.Add (lbnDrive); row.Cells.Add (celImg); row.Cells.Add (celText); tblDrives.Rows.Add (row); return; } private void displayDrives () { string [] arrDrives = Directory.GetLogicalDrives(); for (int i = 0; i /// Required method for Designer support - do not modify /// the contents of this method with the code editor. /// private void InitializeComponent() { this.Load += new System.EventHandler(this.Page_Load); } #endregion private void ImageButton_Click (object sender, ImageClickEventArgs e) { Response.Write("Click event received."); } }
