The RowHeaderMouseClick event[^] only fires when you click on the row header, not when you click on the row itself. There isn't an event that's raised when you click on a row, but you can use the CellClick event[^] to fake it.

Hi,
I am getting the above mentioned error when I am running my application, this application have been downloaded from my company Git location, I have installed Node and npm, those things are sorted out, except few components under npm folder are showing yellow sign that they are not installed yet. But I am not sure why is this error showing up when I am running the application. And another thing is I don't have Admin privileges on the same machine I am running the app, is it something because of that I have no idea - any help would be very very helpful.
Again the error message here:
The reference assemblies for framework ".NETFramework,Version=v4.6.2" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend. CustomerServiceWeb.Selenium.Test

The error message is telling you that you need to upgrade your version of .NET. If you cannot do it yourself then talk to your manager or system administrator.

It is saying that, but actually the problem was different, it was resolved when I made certificates off and installed the npm though. I have installed it from Nuget Package Console, I think which is better.

That usually indicates you're running an application that targets 4.6.2 on a computer which has a later version of .NET installed, and doesn't have the correct targeting pack.
You can download the 4.6.2 pack from Microsoft, but you'll probably need an administrator to install it for you:
Download .NET Framework 4.6.2 Developer Pack[^]
Packs for other framework versions are available here:
.NET SDKs for Visual Studio[^]

Just checking, why is my message is under review buddy, did you set up any filters for me?

Help me to understand what I'm saying, and I'll explain it better to you

Why is it only with me? Like am I a terrorist or what? If there is any terrorist currently in the World, its our Indias Prime Minister Narendra Modi, he killed or let killed 1000s of people for his benefit in Gujarat.
It didn't happen to me in the past, just for saying against a mass murderer, my postings are being filtered, is CP an independent platform of Well educated people or run by the government of Saudi Arabia to punish people who speak openly?

It is not only with you. I can tell that.

Don't dramatize. You are not being censored, you have just been caught by a spam filter that is in continuously improvement. Your message has needed a human "go" to be posted, but your freedom of speech has never been in risk.
CP has a pretty big user database. Spammers are always trying to post their crap here and the filters and the volunteers are the only defense. Please be understanding.

But this never happened to me in the past, can't you please use some better words than dramatizing? Now you know that I am not a spammer, you defense yourself Sir, but when you know that a person is not a spammer, can you please remove the filters now? What is stopping you from doing it?

Individual posters are not addressed by spam filters, they are a RULES based system and cannot be refined to suit 1 person in millions.
Oh and don't post the entire error message in the heading. Do you see anyone else posting multiple lines as their heading?

Hi Holmes, thanks for the reply my friend
Quote: Oh and don't post the entire error message in the heading. Do you see anyone else posting multiple lines as their heading?
I have not seen many peoples posts as I don't like to put nose into some others issues until I really need to read about that topic.
Do you think, is that the reason why I am being spammed here in this post? Actual post didn't give me any filters though, I got hit by the filter when I was responding to Richards answer - anyways, I felt like alienated man, I felt it bad buddy. I am feeling like somebody is pointing at me my friend.

It would not have been your header but something in your response content.

Oh really I'm pu**y are you human? Be a human first before becoming anything, I guess you're born to human parents at least.
Is no one seeing this? Why are your hands tied up to flag this message?

Go to the Bug&Suggestions forum and ask the admins, if you want.
For me, this topic is ended.

In a vb.net 2010 web form application that uses web form controls, there is a 'process' button where the user can click on the button lots of times.
This causes problems in the application for every time the button is clicked on, that many records are created in the sql server 2016 database.
I would like a solution on how to prevent the user from clicking on the button more than one time. I have a 'click button' code to catch when the button is clixked right away.
But I would like to know what I can do so the user knows they cannot click the button more than once:
1. I could make the button invisible.
2. However I would either like to have a popup message and/or somewhere on the webpage saying they can click on the process button only one time.
Thus can you show me the code on preferable setting up a popup menu? If not, can you show me the code on how to display the message on the web form page?

Make a .CS file with name of ImportExcel.CS
:----
public class FileExt : ValidationAttribute
{
public string Allow;
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
if (value != null)
{
string extension = ((System.Web.HttpPostedFileBase)value).FileName.Split('.')[1];
if (Allow.Contains(extension))
return ValidationResult.Success;
else
return new ValidationResult(ErrorMessage);
}
else
return ValidationResult.Success;
}
}
public class ImportExcel
{
[Required(ErrorMessage = "Please select file")]
[FileExt(Allow = ".xls,.xlsx", ErrorMessage = "Only excel file")]
public HttpPostedFileBase file { get; set; }
}
And Add this code to your controller
:-----
public ActionResult ImportExcel()
{
return View();
}
[HttpPost]
public ActionResult importexcel(ImportExcel importExcel)
{
if (ModelState.IsValid)
{
string path = Server.MapPath("~/library/ExcelFile/" + importExcel.file.FileName);
importExcel.file.SaveAs(path);
string excelConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source='" + path + "';Extended Properties='Excel 12.0;'";
OleDbConnection excelConnection = new OleDbConnection(excelConnectionString);
excelConnection.Open();
string tableName = excelConnection.GetSchema("Tables").Rows[0]["TABLE_NAME"].ToString();
excelConnection.Close();
OleDbCommand cmd = new OleDbCommand("Select * from [" + tableName + "]", excelConnection);
excelConnection.Open();
OleDbDataReader dReader;
dReader = cmd.ExecuteReader();
SqlBulkCopy sqlBulk = new SqlBulkCopy(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);
sqlBulk.DestinationTableName = "ExcelFile";
sqlBulk.ColumnMappings.Add("Userid", "Userid");
sqlBulk.ColumnMappings.Add("Name", "Name");
sqlBulk.ColumnMappings.Add("TelephoneNo", "TelephoneNo");
sqlBulk.ColumnMappings.Add("Address", "Address");
sqlBulk.ColumnMappings.Add("EmailAddress", "EmailAddress");
sqlBulk.WriteToServer(dReader);
excelConnection.Close();
ViewBag.Result = "Successfully Imported";
}
return View();
}
And create view page of ImportExcel method with name of ImportExcel.cshtml and add this code
:-----
@model Models.GeneralModel.ImportExcel
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>ImportExcel</title>
</head>
<body>
<div style="float:right">
<h4>@ViewBag.Result</h4>
@using (Html.BeginForm("ImportExcel", "NewCustomer", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
@Html.TextBoxFor(m => m.file, new { type = "file" })
<button id="submitButton" type="submit">Submit</button>
@Html.ValidationMessageFor(model => model.file)
}
</div>
</body>
</html>

You do realise we can all see you talking to yourself, don't you? 
Quote:
string extension = ((System.Web.HttpPostedFileBase)value).FileName.Split('.')[1];
Lots of problems with that line. For example, what if the uploaded file doesn't contain an extension? What if it contains multiple "." characters? What if the extension is .lsx? Etc.
Try:
protected override ValidationResult IsValid(object value, ValidationContext validationContext)
{
var file = value as System.Web.HttpPostedFileBase;
if (file != null)
{
string extension = System.IO.Path.GetExtension(file.FileName);
string[] allowedExtensions = Allow.Split(',');
if (!Array.Exists(allowedExtensions, ext => string.Equals(ext, extension, StringComparison.OrdinalIgnoreCase)))
{
return new ValidationResult(ErrorMessage);
}
}
return ValidationResult.Success;
}

i have been trying to get my program to start but it keeps refusing to.can anyone help me find a solution to the error below.thanks
This site can’t be reached localhost refused to connect.
Search Google for localhost 58962
ERR_CONNECTION_REFUSED

You're trying to access a web server running on port 58962 of your local machine, but there is on web server running there. We can't access your machine so we can't tell you why that is. Typically you only use non-standard ports when running the site in debug mode from Visual Studio. So either you are trying to access your site outside of VS, or VS's internal web server isn't working for some reason.
