C# - Disable HTML Tag Validation On A Specific TextBox?

Sep 7, 2010

I have a form where one of the fields would allow entry of HTML tags.

<asp:TextBox ID="someID" runat="server" TextMode="MultiLine" />

In this field I have a RequiredFieldValidator validation only. Unfortunately, after any PostBack if the content of any of the fields includes HTML tags or any other potentially dangerous code - the entire ViewState is cleaned.Setting ValidateRequest to false does not help. I'm using IIS 7.5 and .NET 4.0.

Disable Validation In Order To Keep Some HTML On Postback?

Oct 3, 2012

I have a div where I put a lot of stuff on runtime to construct a chart. The user should be able to copy the chart to another div (innerHTML) and then make som adjustments to the original div, which causes a postback. Of cours the cloned div comes back empty.

So I'm thinking of putting the entire innerHTML in a session variable at page_unload, but then I run into the validation problem. I've tried using a hiddenfield as an in-between control, but it's the same, and it seems you can't use the CausesValidation on that control. I've also tried a regular asp:textbox, but the CausesValidation doesn't have any effect.

How to do this? Or any better way all together on the copy-chart issue?

C# - Disable Autocomplete On Html Helper Textbox In MVC?

Mar 11, 2011

I would in normal asp.net use a theme to turn off autocomplete on all text boxes on an entire site. However i cannot do this on MVC because nothing in the theme .skin files seems to work.

I have this in my .skin file:

<asp:TextBox runat="server" autocomplete="off" />

however this does not render at all, of course because this is not how MVC works. Anyway is there any way i can get this sort of thing to work.The site i am trying to do it on is too big to warrant changing every textbox or creating a new HTML helper to solve the issue?

MVC :: Can Set The Unobtrusive Validation Support For Html.TextBox()

Dec 13, 2010

I know the unobtrusive client validation is required using Html.XXXFor to generate the input html. But in my project, I want to use Html.TextBox(), and also want to use unobtrusive client validation. I think you'd better expose a extension method like Html.TextBox(..., ModelMetadata,... ) allow me pass the ModelMetadata manually.

How To Replace Html Tag In Html Editor With Specific String

Feb 9, 2010

anyone knows how to replace a html tag in a string with specific characters:

e.g.

string s1 = "<span style="italic">inluding <span style="bold">other</span> tags </span>";
string s2 = "<span style="italic">inluding </span><span style="bold">other tags </span>";

i want to replace "span" with "bold" to "bOpen" and "bClose" and to replace "span" with "italic" to "iOpen" and "iClose" in both c# and javascript.

i did use regular expression to do that: res = Regex.Replace(res, ".*?", replaceHtmlBold); but it cant match the nested tag and none-nested tag at the same time.

DataGrid - Is Possible To Disable Sorting On Specific Columns

Sep 30, 2010

is it possible to disable sorting on specific columns? 5 out of 7 columns have to be sortable, two not sortable. The columns are created dynamically in code behind, so I think doing this with mark up is out of the question. When I say disabled, I'm hoping that the underline wont show on the column header when you mouse over it.

AJAX :: CalendarExtender - Disable Specific Dates

Dec 15, 2013

This question is regarding one of your article on disabling future dates in [URL] ....

Your code in the above link disables(prevents for selection) dates for selection greater than today.

But I want to prevent users from selecting dates after a particular date say for example-after 13th October 2013, all the dates should be disabled.

I replaced this line

 var c = (new Date).setHours(0, 0, 0, 0);
with
var c = (new Date("October 13, 2013 11:00:00")).setHours(0,0,0,0);

in the javascript file(Extension.min.js).

But still it was disabling dates other than today.

Is It Possible To Use Validation Controls When I Need To Modify HTML When Validation Fails

Mar 16, 2011

Let's say that I have the following HTML for a text box on an ASP.NET page:

<div class="myClass">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>

It is easy enough to add a required field validator to this page like this.

<asp:RequiredFieldValidator ID="valMyTextBox" runat="server" ControlToValidate="txtMyTextBox" ErrorMessage="My Text Box is required."></asp:RequiredFieldValidator>

But I need to modify the HTML slightly if this text box fails validation. I need to add a CSS class to the DIV. So if the user leaves this field blank I need the HTML to look like this:

<div class="myClass error">
<asp:TextBox ID="txtMyTextBox" runat="server"></asp:TextBox>
</div>

Is this possible? I can't figure out if there is a way to write code behind that only fires if this particular validator control fails validation or something. I know I can write code that runs when the entire page is not valid. But I just want this code to run when this validator returns invalid. Hope this makes sense.

Web Forms :: Disable ESC Key Validation?

Oct 1, 2010

I have a page that has a submit button which causes validation and a cancel button which does not cause validation.

When the cancel button is clicked, the button's click event handler is executed with no problem.

I would like the ESC key to do exactly what the cancel button does.

What we do is to trap the ESC key and then raise the click event for the cancel button.

Our code to handle the ESC key works fine except when the page has a validator.

When the page has a validator, the cancel button click event handler never gets called after the ESC key is pressed.

It works fine when the cancel button is clicked.

It also works fine if we do the same thing and trap any other key.

So it has something to do the ESC key and validation.

Web Forms :: Validation To Run When Press One Specific Button

- I'm using a RequiredFieldValidator to check whether the text box is empty. I only wanted this validation to run when I press one specific button.

- I dont want the validation to be done on every button control within a page. For example, i have 2 buttons, one is showing a list of data and another will be checking for an empty text boxes. So, when I click the show list button, I dont want the validation to be run, what I want is the validation to be run on the check empty text boxes button.
