I can't give an answer without seeing some source code. Can you copy the particular statement that is giving you this error?

|
|

<form id="Form1" method="post" runat="server">
<asp:TextBox id="TextBox1" name="TextBox1" style="Z-INDEX: 101; LEFT: 304px; POSITION: absolute; TOP: 72px"
TextMode="MultiLine" Height="136px" Runat=server> </asp:TextBox>
<asp:Button id="Button1" style="Z-INDEX: 102; LEFT: 360px; POSITION: absolute; TOP: 256px" runat="server"
Text="Button"></asp:Button>
</form>
and .cs is
-----------
private void Button1_Click(object sender, System.EventArgs e)
{
string psgpost1 = (TextBox1.Text);
string psgpostText1 = psgpost1.Replace("'", "'");
Response.Write(psgpost1);
string psgpost2 = psgpostText1;
string psgpostText2 = psgpost2.Replace("<", "<");
Response.Write(psgpostText2);
string psgpost3 = psgpostText2;
string psgpostText = psgpost3.Replace(">", ">");
Response.Write(psgpostText);
}
how to remove html quotes?

I would like to help, but don't understand the question, or what you're trying to do.
If you want the user to be able to enter HTML escaped values, you need to add:
ValidateRequest="false"
to your Page Directive.
If you want to display those entries on the webform, you have to use the proper escape sequences:
string psgpostText2 = psgpost2.Replace("<", "<");
|
|
You could also use HttpUtility.HtmlEncode(string) for this.
Replacing a character with the SAME character, as you're doing, is a meaningless operation.
<Added>
I see what's going on. The forum is parsing things for us.
string psgpostText2 = psgpost2.Replace("<", "& lt ;");
The second angle bracket should be the HTML escape code for less-than: ampersand-l-t-semicolon
I've tested it and it works fine.

but,
if i use

< he has to get properputput>yaa.
note: between < and still there is no space. then it is giving error.
like
A potentially dangerous Request.Form value was detected from the client (TextBox1="... testing. <still he is trying ...").

From my previous post:
If you want the user to be able to enter HTML escaped values, you need to add:
ValidateRequest="false"
to your Page Directive.
Like this:
<%@ Page language="c#" Codebehind="WebForm1.aspx.cs" AutoEventWireup="false" Inherits="WebApplicationX.WebForm1" ValidateRequest="false"%>

You can just call me "Tom".
Response.Write() merely appends data to the Response Stream. It does not format the data. You have to format the data.
So if you want your data to contain line ending characters, you have to add the HTML tag for producing a line, which is "<br>".
Likewise, if you want to produce a paragraph, you must emit the "<p>" and "</p>" tags in the correct places.
