How To Preserve Literal Text From Server Side When Displaying On Client Side

Mar 2, 2011

ASP.NET newbie question - fastest fingers!

I have a page that needs to pull some script off the server, including tag info, for the page. Thus:

<html><body>
blahblahblah
<%: Model.TaggedField %>
</body></html>

Problem is, the value of Model.TaggedField may include HTML tags, but the page automatically converts the tag info to <myTag> etc.

What method can I call to make the value of Model.TaggedField be transmitted verbatim to the page?

Create Postback Delay Client Side?

May 14, 2010

I am developing a web page where a user will submit some "Comments" on a form. When they click the submit button, I fire off some javascript that captures their current GPS location, which I store in a visible Text Box (for testing purposes). If the user is updating from a device that doesn't support gps, I add text to my textbox that says "Device does not support GPS".

When I get to the server, using a device that doesn't support GPS, that text comes through just fine. When I use my iPhone, I see the GPS Coords in my textbox, but that textbox value doesn't make it to the server.I'm thinking that there is a 2-3 second delay from the time that the button is clicked to the time that the java finishes retrieving the GPS. So the textbox text isn't set fast enough.I'm wanting to prevent a postback for 3 seconds (for example) to give the javascript time to update the textbox.

Tradeoffs With Client Vs Server Side Postback Handling

Aug 26, 2010

I have a ListView that contains a large collection of rows with textboxes that users can optionally fill out. These textboxes are not databound. When the user clicks "next" i need to iterate over the rows and determine which fields the user has filled out, and then update a sort of "cart" with the data and move to a confirmation page ("you have selected a, g, v, zz, is this correct?" sort of thing).

I can think of two ways to deal with this. The first is, server side, to walk the items in the listview, get the control ID's, save this data to a list, then save it to a database cart table for the next screen to read.I can use jquery to collect all the values client side, then pass it back to the form in a hidden field and use something like Newton.Json to get the data into a similar list.What are the tradoffs of these two approaches?

Javascript - Get Client - Side Script To Execute On Postback (from An UpdatePanel)?

Jul 15, 2010

Basically I want to get some javascript to be sent back to the client and executed from a postback inside an UpdatePanel. Furthermore this is inside of a reusable WebControl. I've tried

this.Page.ClientScript.RegisterStartupScript and this.Page.ClientScript.RegisterClientScriptBlock but Firebug shows that those scripts aren't sent back in the postback's response.

I also tried straight up writing a <script> tag inside the control's main div in the Render method, which does get sent back but isn't executed. I got a hacky solution working, but ideally looking for a cleaner solution. The hack is to add a 1x1 pixel img with width/height set to 0 and use that for an onload event to execute the script and that works, but it seems like there has to be a cleaner way to do this.

AJAX :: ModalPopupExtender: After Postback, Client-side Show() No Longer Works

Mar 23, 2010

I'm using what I believe is a pretty common/boring/generic implementation of a ModalPopupExtender. I'm using client-side JS to show the dialog when the user clicks a link, and hide it if they click "cancel". I only do a postback if they truly want to save the data.

I can click the link to show the dialog, then click the cancel button to hide it, then click the link to show it... ad infinitum. If I decide to save the data via a postback, everything works well, and the dialog is hidden as a result of the postback, all as expected.

However, once the postback completes, my client-side JS show() never works again. Any attempts to click the link fail quietly; no error messages, the dialog just never shows again.

How To Force The User To Have At Least One Selected Checkbox And Postback From Client-side JavaScript

Jul 8, 2010

I have two checkboxes: cb1 and cb2. They are both hooked up to an onClick event which checks if at least one checkbox is clicked. If this is not the case, it throws an alert and reverts the change. If a legal change was made (e.g. cb2 was checked, followed by cb1 being unchecked), the function calls the server function checkChange() which needs the object and eventargs.

I'm having trouble with the following:

Reverting the change: how can i find out which checkbox was clicked without adding an extra javascript function for the second checkbox? This has to be a scalable solution as more checkboxes may be added later.
How do I call the server function checkChange(). I am aware of "this.Page.GetPostbackEventReference" but I am confused as to the parameters it takes.

C# - Client-Side Validation Prvent Manually Postback By JavaScript Eval ()

Mar 8, 2010

I encouter some postback issue when using GetPostBackEventReference. Here is the Scenario:I have a javascript modal popup dialog and got a button in this modal dialog which used to select things (this is NOT an asp:button control)

When this javascript dialog HTML button is clicked, it will call the MS AJAX web service call by the javascript: eval() method. And this MS AJAX web service call is dynamically generated. So the code is like this:

var serviceCall = svcCall + "(" + parameters + ")"; //dynamically generate the MS AJAX web service call here
eval(serviceCall);

//use eval to trigger the MS AJAX web service call

As you may all know, after complete the MS AJAX web service, you can define a callback function to handle the completion:

function OnComplete(result, userContext, methodName) {

//force to call postback manually
eval($(userContext[0]).val()); [code]...

As you can see, this is how I bound the asp:button (i.e. btnSelectUser) 's Click Event to the asp:hiddenfield using the GetPostBackEventReference, and set the registerForEventValidation argument to false. I have also tried to use different ValidationGroup and set the CausesValidation to false.In summarize, I bound the asp:button's Click PostBackEventReference(i.e. __doPostback(....)) to the asp:hidden field's Value attribute, and using javascript eval() to eval this hidden field's value in order to manually trigger postback.

p.s. the btnSelectUser is an asp:button control and used to call out the javascript modal dialog.

Ok, here is the Problem:In the same page, there is some asp:validator, e.g. and , and of coz, when the page run into error, this validator and callout will display to the user. e.g. When the user didn't fill in anything and submit the form, the ValidatorCalloutExtender will display a ballon and tell the user. Imagine one of this ballon/validatorCalloutExtender come out and on top of your screen at the moment.

Then you click the btnSelectUser (asp:button) to show the javascript modal dialog, and in the dialog, you Add some users, and once you hit the SELECT button inside this modal dialog, a MS AJAX web service is trigger as mentioned above, and once this web service is complete, it eval() the asp:hidden field's value (i.e. __doPostback(...))......and do the postback manually.

However, because of the validatorCalloutExtender ballon has display, it somehow cannot trigger the postback in this way, but when I close the ballon/validatorCalloutExtender, the manual postback using eval() is just working fine. Even more strange is that, when the ballon is displayed, the first time I click the SELECT button inside this modal dialog it doesn't fire the postback, however, if I do the same thing again (i.e. open up the javascript dialog, and choose some users, then click the SELECT button again). It able to do the manual postback....and I don't understand why the first time doesn't work.

Javascript - User Control With Client + Server Side CustomValidation; Wrong Client Side Validator Is Picked

Nov 23, 2010

I have a user control which contains a CustomValidator which is used according to whether a RadioButton is checked or not (there are several RadioButtons, I'm only showing the relevant one)

<asp:RadioButton runat="Server" ID="RadioBetween" GroupName="DateGroup" CssClass="date_group_options_control_radio" />
[code]...

There is some client + server side validation code (the server side code does exactly the same thing and is skipped for brevity)

<script type="text/javascript">
function ValidateDateFields_Client(source, args) [code]...

There are two instances of this control in the page. When running the client side version it hits the wrong one (the version of the control which is disabled). You can see from the generated HTML both are correctly specified. I'm not sure how .NET works out which clientside function to call given they both have the same name.

<script type="text/javascript">
//<![CDATA[
var ctl00_MCPH1_QueryTextValidator = document.all ? document.all["ctl00_MCPH1_QueryTextValidator"] : document.getElementById("ctl00_MCPH1_QueryTextValidator");

[code]...
Do i need to add something in to scope it? What's the best way to achieve this? If I disable the loading of the second control everything works fine.

Web Forms :: ASP:TABLE And Get The Postback Data From A Programmatic Generated Radio Buttons In TableCell Object

Sep 13, 2010

I am having a bit of trouble trying to get teh postback data from a programmatic generated radio buttons in TableCell object. I have the following ASP user control:

<%@ Control Language="C#" AutoEventWireup="true" CodeBehind="wcntrlCallFlow.ascx.cs" Inherits="CallEvaluation.wcntrlCallFlow" %>
<style type="text/css">
.TableDev
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
}
.HeaderRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:#33CCCC;
}
.DetailRowStyle
{
width: 100%;
border-style: solid;
border-width: 1px;
border-color: Black;
background-color:White;
}
</style>
<asp:Table ID="tblControl" runat="server"/>

I generate the TableRow and TableCell base off XML data file. When the submit occurs I can not access the data values from the radio buttons that are generated. I try to get the data in the following manner:

if(Request[objRadioName].Checked)
{
this.value = 5;
this.ReCalc();
}

I notice that in the Request object the table row name is passed back like: "wcntrlCallData1$wcntrlCallFlow1$CallFlow".

Changing A Control's BackColor To Match GridView Row BackColor

Feb 12, 2010

VWD 2008 Express. Visual Basic.

I have a gridview control that has a different background color for alternating rows (done using cssclasses). In the RowDataBound event code, I want to change the background color of a ListBox control in one of the cells to match the row color. I have tried the following (in blue), but it does not seem to work. The listbox control still remains with white background. How may I determine the background color of the row so that I may set the ListBox background to match?

[Code]....

A corollary question is, "How may I programmatically reference an item within a CssClass?" For instance the CssClass is named "datagrid." How do I programatically retrieve the value of "background-color" that is defined in this CssClass?

How To Preserve The Index And Make Sure The TabContainer And The TabPanel Is Loaded At Postback

Mar 26, 2010

At first time page load the TabContainer and TabPanel is shown where the default tab index is zero. This panel has some user controls and a "Go" button. The "Go" button loads a GridView is a separate panel. So far things ar good.

Now when I either sort or page throught the GridView, the TabContainer disappears. I read somewhere that the current tab index would be preserved during post back. So how can I preserve the index and make sure the TabContainer and the TabPanel is loaded at postback and still have the information originally entered by users in the controls? Could I use a "Session" variable?

Jquery - Options For Page With Matching Client-side And Server-side Markup?

Oct 17, 2010

Suppose I'm building a StackOverflow clone using webforms ASP.NET and jQuery. The Question page has a question, several answers, and comments under each. Requirements:Users can post new answers and comments, and edit existing ones, without postbacks. No UpdatePanels; the AJAX calls retrieve just the JSON they need, not HTML fragments. The page loads with all existing answers and comments in place (no javascript needs to run to read the page).

What I'm trying to figure out is how to do this without having to maintain two sets of markup (one that's bound on the client using some form of jQuery templating, and one that's bound on the server using traditional WebForms).
