Issues with multiline textbox, javascript and IE


Hi All,

i have a requirement to embolden/italicise the selected  text in a textbox. the way it is implemented as is by using a js function which inserts <b> and </b> tags at the start and end of the selected text  for bold, and similarly <i> and </i> tags at the start and end of the selected text  for italics.

here is the code in c# (to add attributes to link buttons)

lkbBold.Attributes.Add("onclick", "AddHTMLTags('" + txtTitle.ClientID + "', 'B'); return false;");
lkbItalic.Attributes.Add("onclick", "AddHTMLTags('" + txtTitle.ClientID + "', 'I'); return false;");

the txtTitle is the id of the text box, which contains the selected text to be emboldend.

and here's the javascript method

function AddHTMLTags(textBoxId, format)
  var textComponent = document.getElementById(textBoxId);
  var selectedText;
  var textToReplace; 
  var content = document.getElementById(textBoxId).value;
  var content1 ;
  var content2 ;
  var newContent; 
      // For IE 
      if (document.selection != undefined)
        var len =  document.selection.createRange().text.length;
        var myrange

Javascript to update value in Textbox

Hi I have a javascript file, which creates a calendar picker. This file is used through out the application and is a piece of code that I have to use because my .Net application is part of another application which uses this piece of JavaScript code.Anyhow, with the calendar picker I can save the date into a textbox, but the problem that I have is the format. Unfortunately, I cannot change the calendar picker code because this will affect other parts of the application. Therefore, what I am looking to do is to reformat the date on the textbox control. This I can do but only when I use the javascript event onfocus.Now, my question is this, is there away in javascript or with jquery that when a value enters into a textbox that this value is then reformatted to the format I want without postback or clicking on the textbox?Thanks

Problem with JavaScript on Textbox

 I have a textbox which is populated by an external javascript file which I cannot alter without affecting another part of the system. What I would like to do is once this textbox has a value to do something with it. The javascript that I want to use is fine, but it won't automatically when a value has populated it i.e. onchange. It will work when the event is onfocus. Is there away in which I can automatically fire off my javascript event when a value has entered the textbox from another piece of javascript code?

Javascript funtion working in FF but not in IE

Hi I have a button control on click of which a javascript funtion is called but this function is calling in FF but not in IE7. Can you please suggest what are the possible ways to overcome it. <cc1:MessagizedButton ID="btSave" runat="server" OnClickClientHandler="_s.widgets.editSavedSearchWidget.saveData();return false;" IsLinkButton="true" IsRegisteredOnClient="true" />  and the funtion is: Note: Even the alert('b') is not calling but calling in FFsaveData: function() { alert('b'); var var_value = $("input[name='savedSearchEditOpt']:checked").val(); var data = ""; //alert(var_value); //show spinner $('.wdgEditSpinner').show(); if (var_value == null) return; if (var_value == 1) { data = true; } else { data = false; } _s.services.imonsterWidgets.updateUserWidgetAttribute(_s.imonster.userWidget.allWidgets.savedsearches, _s.imonster.userWidget.widgetAttrids.edit, data, _s.widgets.editSavedSearchWidget.onSaveSuccess, _s.widgets.editSavedSearchWidget.getError); },

javascript to hide ModalPopupExtender not working

Hello, I've seen some other posts about this but never found a resolution to it. I have a gridview control with another gridview inside each row. I'm using a masterpage and I have a TabContainer to boot and of course updatepanels. I'm showing my gridview child via a modal popup extender. It shows great and other JQuery operations are working as expected. I have a pageLoad javascript that does the following: function pageLoad(sender, args) {      $addHandler(document, "keydown", OnKeyPress);   } And, function OnKeyPress(args) {      if (args.keyCode == Sys.UI.Key.esc) {         var mp = $find('<%=mpe1.clientid%>');         mp.hide();      }   } The var mp seems to be returning an object as '<%=mpe1.clientid%>' returns the clientid, and the mp.hide() line executes without error. It doesn't hide the popup however. What can be the problem?S

Not able to bind textbox with javascript textbox? Why?

I'm trying to use a javascript Date and Time calendar in my Insert and Edit templates in a Detailsview that is bound to SQL Fields. The reason I am trying the javascript date time selector is that I need to have the date and time, the asp.net one is just the date part. I guess my first question is this possible? I tried using it with an asp:textbox on just a plain aspx page and it works like a charm, however when I add it to the detailsview i keep on getting the "Error: Object required"  am I missing a step here?  That and seeing as I'm using a site master page where exactly do I put the:  "<script type="text/javascript" src="datetimepicker_css.js"></script> "   <asp:TemplateField HeaderText="Start Time" SortExpression="StartTS"> <EditItemTemplate>   <asp:TextBox ID="STEditCalendartxt" runat="server" Text='<%# Bind("StartTS") %>'>    </asp:TextBox> <a href="javascript:NewCssCal('STEditCalendartxt','mmddyyyy','arrow',true)"> <img src="images/cal.gif" width="16" height="16" alt="Pick a date"></a>  </EditItemTemplate> Any assistance would be greatly welcomed.

Disable copy paste in textbox without Javascript

TextBox AutoPostBack not working when handling other DHTML event


I have to format a number in a TextBox while it is being typed. Right after the TextBox looses focus, I need to do other processing on server side, including some database queries.

I'm doing the formatting by handling the onkeyup event, client side. But when I add the handler, the onTextChanged event stops firing on the server. I've tried different return values for the handler but unfortunatelly I'm stuck.

To reproduce the problem, here is a sample where the formatting function was replaced by a simple "convert to uppercase" function. You'll see that, contrary to the expected, the Label doesn't get filled when the TextBox looses focus. It does get filled, however, if the user presses the ENTER key.

What can I possibly be doing wrong with such a simple task?


<%@ Page Language="VB" %>

<script language="VB" runat="server">

Sub Page_Load(ByVal Sender As Object, ByVal E As EventArgs)

'' Adding the event handler like this has the same effect as adding it inline

'txtTextBox.Attributes.Add("onkeyup", "return(upperCase(this));")

End Sub

Protected Sub txtTextBox_TextChanged(ByVal sender As Object, ByVal e As System.EventArgs)

lblTextBox.Text = S
