copied!<p>I have a large application and I'm going to enabling short-cut key for it. I'd find 2 JQuery plug-ins (<a href="http://jonathan.tang.name/files/js_keycode/test_keycode.html" rel="nofollow noreferrer">demo plug-in 1</a> - <a href="http://code.google.com/p/js-hotkeys/" rel="nofollow noreferrer">Demo plug-in 2</a>) that do this for me. you can find both of them <a href="https://stackoverflow.com/questions/593602/keyboard-shortcuts-with-jquery">in this post in StackOverFlow</a></p> <p>My application is a completed one and I'm goining to add some functionality to it so I don't want towrite code again.</p> <p><strong>So as a short-cut is just catching a key combination, I'm wonder how can I call the server methods which a short-cut key should fire?</strong></p> <p>So How to use either of these plug-ins, by just calling the methods I'd written before? Actually How to fire Server methods with Jquery?</p> <p>You can also find a good article <a href="http://encosia.com/2008/05/29/using-jquery-to-directly-call-aspnet-ajax-page-methods/#comment-39102" rel="nofollow noreferrer">here, by Dave Ward</a></p> <hr> <p><strong>Update:</strong> here is the scenario. When User press CTRL+Del the GridView1_OnDeleteCommand so I have this</p> <pre><code>protected void grdDocumentRows_DeleteCommand(object source, System.Web.UI.WebControls.DataGridCommandEventArgs e) { try { DeleteRow(grdDocumentRows.DataKeys[e.Item.ItemIndex].ToString()); clearControls(); cmdSaveTrans.Text = Hajloo.Portal.Common.Constants.Accounting.Documents.InsertClickText; btnDelete.Visible = false; grdDocumentRows.EditItemIndex = -1; BindGrid(); } catch (Exception ex) { Page.AddMessage(GetLocalResourceObject("AProblemAccuredTryAgain").ToString(), MessageControl.TypeEnum.Error); } } private void BindGrid() { RefreshPage(); grdDocumentRows.DataSource = ((DataSet)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.TRANSACTIONS_TABLE]; grdDocumentRows.DataBind(); } private void RefreshPage() { Creditors = (decimal)((AccDocument)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.ACCDOCUMENT_TABLE].Rows[0][AccDocument.ACCDOCUMENT_CREDITORS_SUM_FIELD]; Debtors = (decimal)((AccDocument)Session[Hajloo.Portal.Common.Constants.Accounting.Session.AccDocument]).Tables[AccDocument.ACCDOCUMENT_TABLE].Rows[0][AccDocument.ACCDOCUMENT_DEBTORS_SUM_FIELD]; if ((Creditors - Debtors) != 0) labBalance.InnerText = GetLocalResourceObject("Differentiate").ToString() + "‏" + (Creditors - Debtors).ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF) + "‏"; else labBalance.InnerText = GetLocalResourceObject("Balance").ToString(); lblSumDebit.Text = Debtors.ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF); lblSumCredit.Text = Creditors.ToString(Hajloo.Portal.Common.Constants.Common.Documents.CF); if (grdDocumentRows.EditItemIndex == -1) clearControls(); } </code></pre> <p>Th other scenario are the same.
