They use classes instead of enums.

Of course there is no such things as a "best" solution. However, if you are unable to use existing libraries, such as SignalR, then you need to use the manual approach which means doing it in JavaScript as you mentioned.
If you can do jQuery that should help you a lot.

Typically, your code won't change much as long as you write good code to begin with. Handling an increase in load is done by configuring servers, not changing code.

Hi all,
I am very new to ASP.net MVC.
I am creating a simple web application and want capture and save the userID to a newly created record by the user.
The reason is, I want users only can edit the records they created if not their record then only can view (except for the admin ofcourse).

It is not clear what is the question.
I beleive getting the current username inside a controller can be done like this:
Username = User.Identity.Name
|
|
|
|
|
Thanks so much for the respond.
Part 1. Get the user ID.
Part 2. Write the user ID to the Database (server side)
So, Username = User.Identity.Name is to get the user ID.
Now how do I write the user ID to the table (the database).
|
|
|
|
|
I'm really not that familiar with MVC development, but I believe the SQL necessary to store the UserID would be in a "Model".
|
|
|
|
|
Does anyone have a sample code for me to write UserId to the table (database server side)?
Help.....I stuck

I want validation code in separate js file and include it on content page in asp.net
How can I use controls on content page with js file ?
Please provide solution with custom example.

Your question contradicts the title
Your should probably use jquery first
So you right click on solution exploer, add file JScript, and name it validate.js
Then create a function
function validate_text() {
var vFlag = true;
var txtFocus = 'rgb(255,255,255)';
var txtError = 'rgb(255,0,0)';
var message_value = $('[id*="_txt_CRM_VCM_MessageReply_Field"]').val();
if (message_value.length < 2) {
$('[id*="_txt_CRM_VCM_MessageReply_Field"]').css('border', 'solid 1px ' + txtError);
vFlag = false;
}
else {
$('[id*="_txt_CRM_VCM_MessageReply_Field"]').css('border', 'none');
}
return vFlag;
}
On your Button, program the OnClientClick property
<asp:TextBox ID="_txt_CRM_VCM_MessageReply_Field" runat="server"></asp:TextBox>
<asp:Button ID="Button1" runat="server" Text="Button" OnClientClick="return validate_text(); " />
Now drop in your jquery, this will dowmload jquery to the page for use in your validate.js
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
or download jquery and create a jquery.js file where you placed your validate.js file
Make a reference to validate.js
Use the solution explorer and drag the file to within the head tags, and the script tag will automatically be formed.

I have a page like this:
<%@ Page Title="test" Language="C#" MasterPageFile="~/Template.master" CodeFile="Define.aspx.cs" Inherits="JobRecords_Default" EnableEventValidation="false"%>
<script type="text/javascript">
function changeFunc() {
var selectBox = document.getElementById("selectBox");
var selectedValue = selectBox.options[selectBox.selectedIndex].value;
window.location.href = '?s=' + selectedValue;
}
</script>
<form role="form">
<label>Ward:</label>
<select id="selectBox" class="form-control" onchange="changeFunc();" runat="server">
<option value="1">Ward 1</option>
<option value="2">Ward 2</option>
<option value="3">Ward 3</option>
</select>
<asp:Button ID="btnRegister" CssClass="btn btn-lg btn-block btn-success" runat="server" Text="Register" OnClick="btnRegister_Click" ></asp:Button>
</form>
I want to use
changeFunc() in my selectBox onchange event 
If in the first line I set EnableEventValidation to false changeFunc() wont fire and if I set EnableEventValidation to true after clicking the btnRegister I will see below error:
Quote: Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation.
is there any one who can help???

True!
The problem is that you do not initiate post-back but change location...That makes ASP.NET engine think that you are not you!
The best you can do is to use DropDownList[^] control of ASP.NET...
I'm not questioning your powers of observation; I'm merely remarking upon the paradox of asking a masked man who he is. (V)

Have a look into AddWithValue[^]. your syntax is wrong, the .VALUE is invalid in the constructor.

Those are two different variables. You're getting a NullReferenceException because you haven't initialized the cmd variable.
Change your code to either:
cmd1.Parameters.Add("@ApplicationID", SqlDbType.UniqueIdentifier).Value = appIDValue;
or:
cmd1.Parameters.AddWithValue("@ApplicationID", appIDValue);
Other comments:
The SqlDataAdapter class takes care of opening and closing your connection for you, so there's no need to explicitly open the connection before calling the Fill method.
The SqlCommand constructor has already assigned the connection; there's no need to set da1.SelectCommand.Connection to the same connection instance.
You should also look at wrapping your connection and command objects in using blocks, and avoid storing them in fields.
using (SqlConnection con = new SqlConnection(connectionString))
using (SqlCommand cmd = new SqlCommand("[sp_ReadPreviousProperty]", con))
{
cmd.CommandType = CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@ApplicationID", appIDValue);
SqlDataAdapter da1 = new SqlDataAdapter();
da1.SelectCommand = cmd;
DataSet ds1 = new DataSet();
da1.Fill(ds1, "tblPropertyMaster");
return ds1;
}
Finally, using sp_ as the prefix for a stored procedure is not a good idea:

But only the data in current grid was captured using the following method
mya=jQuery(”#list2″).getDataIDs(); // Get All IDs"
If I like to export all data (e.g. totally 18 records, 10 displayed in current grid and 8 in second grid page), is there a way to capture all 18 records without invoking the backend?
i am not finding any solution only first page data is capturing in excel ...
I am using
var jqgridRowIDs = $(tableCtrl).getDataIDs(); // Fetch the RowIDs for this grid
var allJQGridData = $(tableCtrl).jqGrid('getRowData');
var headerData = $(tableCtrl).getRowData(jqgridRowIDs[0]);
Plz help me out.....
