HTML - Encoding A Field Within A Gridview?
Apr 4, 2012
I have some of these events in my gridview custom coded. But the real issue here is that I store a previous record, that is, the record that was being changed, or the old.value and I store it in another column. So when the user enters say "< newValue >" without the quotes, the aspx validator rejects the input as dangerous.
I can disable the validation, and html encode the value as it gets written to the db, but when I display the value back in the gridview in the "Previous Value" column it appears like this...< Neutral > semi-colons missing because this site decodes.How I can encode and decode inline in ASPX?How can I encode this template field that is getting entered into a gridview?
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("lang_String") %>'></asp:TextBox>
</EditItemTemplate>
allow certain html characters to be entered into this field only without turning off validation for the entire site.I do need this to apply to the entire column.

I have to submit a HTML form to a 3rd party website and one of the hidden fields is an XML string. The XML needs escaping before it is sent to the 3rd party.
However when I add the plain XML to the form field it semi-escapes it for me. So then when I use HTMLEncode myself part of the XML is double-escaped. How do I prevent the automatic escaping that appears to becoming from .NET.
Or even better how else can send the escaped XML via the hidden field.
XML
<systemCode>APP</systemCode>
Basic assigning to hidden input field
<systemCode>APP</systemCode>
When I HTML Encode it as well
&lt;systemCode&gt;APP&lt;/systemCode&gt;
I can see what's happening - but I don't know how to prevent it?

There are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

I want to save a HTML file to MHT file. Now, it is done with CDO object I googled. But, I want to save the MHT file with indicated encoding by myself. For example, the content in HTML file are Chinese word; if I save as the HTML to MHT in IE, the content in MHT are encoded by GBK (it are hex word instead of Chinese word); if I save as the HTML to MHT with CDO object, the content in MHT are Chinese word.

I am having a constant series of problems with encoding characters for output in an XML file through .NET. I have a feeling that the problem relates to a setting on the Response object being used but I'm unable to get anywhere finding the correct setting. If I do the following:
system.web.httpcontext.current.response.write("€ & ™" & server.HTMLEncode(" € & ™ "))
I get the following output:
€ & ™ € & ™
The question is why are standard ASCII characters encoded, but the extended(?) characters not? Is there some kind of setting I need to give to the server object to tell it to convert characters like Euro/Trade Mark?One of the bullet points of MSDN's HTMLEncode function page states that: Any ASCII code character whose code is greater-than or equal to 0x80 is converted to &#, where is the ASCII character value.

In the RowDataBound event of an ASP.NET Gridview I am trying to read the value of a Label in a Template Field. I would prefer to capture this value in the RowUpdating Event, but for some reason I seem to recall that it is not possible. Here is the ASP...
<asp:TemplateField HeaderText="Translation" ItemStyle-Width="250" >
<ItemTemplate>
<asp:Label ID="Label11" runat="server" Text='<%# Bind("lang_String") %>' Width="250px"></asp:Label>
</ItemTemplate>
Here is the VB.net code that I am trying to figure out....
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If (e.Row.RowState And DataControlRowState.Edit) > 0 Then

I want to populate a checkbox field in a gridview.
I am using the Checked='<%# Convert.ToBoolean(Eval("Inactive")) %>' statement but the issue that I am facing is that in the database some records contain NULL for Inactive. If it encounters a 0 or 1 value it works fine but if NULL it throws an exception.
Kindly guide me how to populate the checkbox so that it should be unchecked even if the field is null.

I have a gridview that displays a calculated field, based on a db source field it populates with.
can i sort by it? i can't seem to figure out how to do it?
example:
my templatefield looks like this:
<asp:TemplateField HeaderText="Category" SortExpression="category" >
<ItemTemplate>
<asp:Label runat="server" Text='<%# BuildCategory(DataBinder.Eval(Container, "DataItem.category")) %>'
ID="lblPrice"></asp:Label>
</ItemTemplate>
</asp:TemplateField>
where category is party of the datasource, but what gets displayed is a calculated value - which is different from the category.what can i put in the "SOrtExpression" to make it sort by the new value - taht gets displayed?

I have a page which has a GridView on it, which is populated from a database. Some of the columns in the GridView have text boxes, as well as Checkboxes.When the user saves the page, the page may error if they have not entered their data correctly. At this point, I need to re-display what they have entered already so they can simply make the correction instead of having to change everything from scratch again.

As you can see I was playing with WithEvents but that didn't seem to help. In the above code all I was trying to get was some kind of reaction to the clicking of a checkbox - but nothing happens (no errors, either).

This may sound really stupid but I have to ask cause I'm not finding this answer anywhere.I have an application where the user will need to sign up for a new user account on the website [URL]..However when I am using Firefox's plug-in Firebug to view html I am getting something totally different than when I just right click on the site and view the page source.
What I am trying to do is to get the captcha from the website and display it in a picturebox on the application so the user can view the captcha, solve the captcha and then the app post is back to the service for a response.
Here is the source that I am getting using Firefox's Firebug to inspect the element:
<td>
<input type="hidden" value="Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK" name="iden">
<img class="capimage" src="/captcha/Oo3Jo1I8bgzK68agMqo3s79ZZib2OkbK.png" alt="i wonder if these things even work">
</td>
[Code]...
Why would the two be showing me two different versions of the HTML?
And how would you be able to grab that source to view in a picturebox using webclient?

Usage: Users create pretty HTML news letters in another app. They post the newsletter to the web, but they also want to set the contents of the HTML news letter file as the body of an email and send it using Application In Question. The users understand to use absolute link and image references when sending an E Newsletter. Environment:
AIQ is a VB.Net app deployed via ClickOnce. It is an intranet app; one can be sure MS Office 2003 and the interop 11 dlls are on the target machines.
Restrictions: MAPI is out. It mangles the HTML. Since it is a ClickOnce deployment, we can't register dlls (I think, correct me if I am wrong). Therefore CDO and COM is out (again, I may be wrong.... I would be happy to be proven so).
