I have a checkbox panel and I am adding the text for check box like this

chkPanel.Controls.Add(new CheckBox { Text = "Savings" + "This text needs to be red and bold", Checked = true, Enabled = false });
chkPanel.Controls.Add(new LiteralControl("<br />"));
chkPanel.Controls.Add(new CheckBox { Text = "Checking" , Checked = false, Enabled = false });


where you see "This text needs to be red and bold"  i actually want that text to be red and bold.  is it possible. if yes how?

Hi,

I recently ran a Nessus scan and have been working through the output, I'm trying to is how to fix one of the vulnerabilities

The web server running on the remote host appears to be using Microsoft ASP.NET, and may be affected by a denial of service vulnerability. Requesting a URL containing an MS-DOS device name can cause the webserver to become temporarily unresponsive. An attacker could repeatedly request these URLs, resulting in a denial of service. Additionally, there is speculation that this vulnerability could result in code execution if an attacker with physical access to the machine connects to a serial port.

Solution
Use an ISAPI filter to block requests for URLs with MS-DOS device names.

I have been researching how to resolve this but can't find the answer, do I need to install a Microsoft patch or something, any help would be appreciated

The server is running 201r2

I have an ASP.NET Web Site built in .NET 4.7 using C#. In my web.config, I have the following Forms authentication (see web.config below) with the "domain" attribute set to ".mydomain.com" for my Production environment. Is there a way to dynamically change its value (via C#)  based on the environment, such as QA, Staging, etc. For example, if (Request.Url.AbsoluteUri.StartsWith("http://qa")), then I want to change the value of the "domain" attribute to ".myqadomain.com", and  if (Request.Url.AbsoluteUri.StartsWith("http://staging")), change the value to ".mystagingdomaincom".

Here's the <authentication> section of my web.config:
    <authentication mode="Forms">
      <forms path="/" name="MyWebSite_Auth" loginUrl="~/login.aspx" defaultUrl="~/customers/Default.aspx" protection="All" slidingExpiration="true" domain=".mydomain.com" timeout="350" cookieless="UseCookies"/>
    </authentication>

Please provide the necessary C# code to accomplish this.

Many thanks in advance.

Hello Experts,

I 'm new to JQuery and using Datatable(3rd party o plug-in) to show data(grid style) on the page. Once the record is inserted I want to update the grid(new record is inserted via button click which opens modal popup and later I'm refreshing the grid). But I'm getting "Not available" when destroying the datatable so I rebuild it again with new data. Below is the sample code.

HTML

<div class="table-responsive m-t-40">

                    <table id="dataTable" class="display nowrap table  dataTable" cellspacing="0" width="100%">
                        <thead>
                            <tr>
                                <th>First Name</th>
                                <th>Last Name</th>                               
                                <th>Phone</th>
                                <th>Email</th>                              
                            </tr>
                        </thead>
                        <tbody id="tblbody"></tbody>
                    </table>
                </div>

JavaScript

 $("#tblbody").empty();

                            data = JSON.parse(data);
                           $('#datatable').datatable().destroy(); -- Error here on  on Quick watch the value is "not available"
                            
                             -- Rest of the code doesn't execute due to error     
                            var html = '';
                            for (var i = 0; i < data.length; i++) {
                                var obj = data[i];

                                html += '<tr>'
                                html += '<td>' + obj.FirstName + '</td>';
                                html += '<td>' + obj.LastName + '</td>';                             
                                html += '<td>' + obj.PhoneNumber + '</td>';
                                html += '<td>' + obj.Email + '</td>';                                                                 
                                html += '</tr>'
                            }

If I comment $('#dataTable').DataTable().destroy() and try the above code I get a Warning message(popup) on the page and also tried $('#dataTable').DataTable().clear() it doesn't throw error but I got the same warning. Attached is the warning message.

I'm trying to post to an HttpHandler ashx file with parameters.

function sendClickData(methodName,paramValue) {
    
    try {
        // create web service param object
        var passUrl = "SetGridDefaults.ashx";

        // save data to web service using an ajax post method
        $.ajax({
            type: "POST",
            url: passUrl,
            data: "MethodName=SetDefaultGridView",
            success: function (data) {

            },
            error: function (error) {
                alert(error);
            }
        });
    } catch (e) { }

}

Select all Open in new window

In the data row, I am passing values to be retrieved as query strings:

In my ProcessRequest, I am retrieving the value:

  Public Sub ProcessRequest(ByVal context As HttpContext) Implements IHttpHandler.ProcessRequest

        Dim method As String = context.Request.QueryString("MethodName").ToString()

Select all Open in new window

When I run it, it gives me an error that the MethodName is null on the request.querystring line of code:
>>An exception of type 'System.NullReferenceException' occurred

This code was from an original article here:
original code

The only thing I see different is that it says to include an older version of jquery - version 1, whereas I am using version 3.

Also, in addition, I would like to pass two values if possible.

And yes, I know I can use a web service or API, but I was hoping I could use this, since it's just a very simple request.

Thanks!

I have a dataTable that I am building that switches between tile and list view. On the tile view I have inserted a row that is a new button which users can click to insert a new user. When the table is returning the number of records in the table it will include the NewButtonRow in the count.
For example, in the simplified table below I have one record, but the number of records returned will be 2 because of the NewButtonRow.

 <table id="TableTeamGrid">
            <thead>
                <tr>
                    <th>
                    </th>
                </tr>
            </thead>
            <tbody id="dataContainer" clientidmode="Static" runat="server">
                <tr id="NewButtonRow">
                               <td class="stylAddNewBtn"></td>
                </tr>
                <tr id="TileRow">
                               <td></td>
                </tr>
  </tbody>
 </table>

Select all Open in new window

I need it to show 1(START) of 1(MAX or TOTAL) in the case of the simplified table above instead of 1(START) of 2(MAX or TOTAL).
I am using this dataTable here: https://datatables.net/.
These are the settings I have for the table:

$(document).ready(function () { 
  $('#TableTeamGrid').DataTable( {
"ordering": true,
"order": [ 1, 'asc' ],
"stateSave": false,
"serverside":   false,
"autoWidth": false,
"language": {
"lengthMenu": '<select>'+'<option value="10">10 per page</option>'+'<option value="20">20 per page</option>'+'<option value="30" selected>30 per page</option>'+'<option value="40">40 per page</option>'+'<option value="50">50 per page</option>'+ '<option value="-1">All</option>'+'</select>'  ,
"info": "_START_ of _MAX_"  ,
"paginate": {
"previous": "<<"  ,
"next": ">>" 
 }
 } ,
"pageLength": 30 ,
scrollResize: true,
scrollY: false,
scrollX: true,
scrollCollapse: true,
"dom": '<"stylTableMenu"filp>tB'

Hello,

I am getting the following error when attempting to add more than one record to a table.

System.Data.SqlClient.SqlException: 'Violation of PRIMARY KEY constraint 'PK__AOP6__3214EC075FC67488'. Cannot insert duplicate key in object 'dbo.AOP6'. The duplicate key value is (0).

Any ideas what is causing this error?

I am working on an ASP.NET application.

The Design window of VS2019 does not render correctly CSS3, like grid or flexbox. Or it only understands the old CSS. (?)

While this may not be important (one can view page in browser), still I may be missing some setting... Is there a way or option I can set for CSS3 in VS2019?
