MVC :: Executing Html.TextBox In Controller Code?
Feb 17, 2010
I can't find the namespace where it's stored - in the view code I can execute Html.TextBox(<name>, <contents>, <html attribs>) and Html.DropDownList(<name>, <select list contents>, <html attribs>) but how do I execute these methods in controller code?
In case you are wondering why on earth I want to do this, rather than using the TextBox object, I execute Html.TextBox(....).ToString() and create html code from these objects.

I pick up on the nerddinners examples, following Professional.ASP.NET.MVC wrox book. but now i'm doing some modifications for my own account. On traditionl ASP.net it was possible to interact with html elements (divs, textbox, etc... )On MVC 2 is that possible or any interaction with html must be done with jquery and how? Because i'm trying to manipulate an html element on my Controller page(DinnerController.ASPX and i had no reference to html div, as i initially supose.

I have some static (pure html) pages in my MVC application that I need to authenticate, so that not just anybody can look at them. Is there an way to do this without moving all the code to asp files and adding a controller and from there use the Authorize attribute? I would really prefer to not need to do this!

I have a textbox which I need to enter html code into (like < strong> or < em> for example).The trouble is this is causing an error writing this back to the database. A potentially dangerous Request.Form value was detected from the client (tbVOther="< strong>testIs there a way around this without turning off the request validation setting?

I just finished building a new version of a web app that imports custom-formatted documents. However, now I just found out that I need this web app to also import custom documents from 3 years ago. I have the code from 3 years ago that imports the older docs...
I was wondering if I could put some type of "if then" statement in my code like " If oldVersionofDoc Then...execute the old code located in this .vb file".

I'm using the following code in an attempt to show a dialog with a list of errors on the client:
if (rollout.ImportErrors.Count > 0)
{
ClientScript.RegisterClientScriptBlock(GetType(), "showErrors", "showErrors();", true);
}
The error count is non-zero and the following script block is emitted, but the script isn't executing.
<script type="text/javascript">
//<![CDATA[
$("#error-report").dialog("open")//]]>
</script>
If I call the function directly from a Firebug console window, the dialog shows properly, so I know the dialog and my code are working. BTW, this code is in a content page, using a content placeholder that 'injects' code into the element of the rendered page.

[Code]....
I then decided to run the whole thing on the server it uses the same code above but I now have several parameters to pass in and call a slightly different stored procedure
DataSet dsEx = new DataSet();
SqlCommand testcommand = new SqlCommand();
testcommand.CommandText = "spLockUnlock";
testcommand.CommandType = CommandType.StoredProcedure;
testcommand.Connection = sqlLockUnConn;
testcommand.Connection.Open();
testcommand.Parameters.Add("@OffState", SqlDbType.Varchar);
testcommand.Parameters["@OffState"].Value = ViewState["OffState"].ToString();
testcommand.Parameters.Add("User",SqlDbType.Int);
testcommand.Parameters["@User"].Value = lblUserID.Text;
testcommand.ExecuteNonQuery();
testcommand.Connection.Close();
rest of the code follows
The stored procedure uses the parameters to lock certain records, then I use exec spOfflineSystem which executes a series of select statements (as above), then I unlock the records afterwards....no problems however my dialog box on the front now reads
CustomersEC45TG.xml
If you step through the code the filename reads Customers.xml yet on the front end we get the spurious characters....each time this is executed the spurious characters are different. Only every now and then will the correct filename dialog box show.

Here is what I need to do: I need to execute some server side code after a user clicks on a button, THEN I need to execute some client side code. OnClientClick gets invoked BEFORE the onClick; and what I need is the opposite.
Is there a way to do this? It looks like I will have to execute JS code from the server code.

I have a web project that sends out a customized email after certain user events (like a status change). I also have an SSIS package on the database that pulls in data from one database and updates another database with that data. I want to be able to compare the data and if a particular field's data for that record is different between the two databases is different, I want to be able to use the dll I created for the web app to send the appropriate email.

I am beginner to .Net development, so i am looking for a favour.
Question 1 :
protected void Page_Load(object sender, EventArgs e)
{
txtUserName.Text = "Focus";
txtUserName.Focus();
}
I am unable to get focus to my textbox
Question 2 :
I made javascript code for client side validation.
function loginjs()
{
if(document.getElementById('txtUserName').value.length==0)
alert("UserName cannot be blank");
else if(document.getElementById('txtPassword').value.length==0)
alert("Password cannot be blank");
}
this code executes but it is not stopping further code execution. I mean it is only alerts but in addition to that i need to stop further execution.

I have a Global.Asax and Global.Asax.cs file that is specific to my particular Asp.net project. For some unknown reason the code in my Global.asax.cs file is not being executed. I thought that the breakpoints were being ignored, however that is not the case. Because if I try to deliberately force an error to occur, the code is never executed. Below is an example of what I am talking about. The real code in my Application_Start method is not shown below. ANd other methods are not shown as well.
I have tried renaming the Global.asax file and then re-creating it, and that did not work either. Strange because when I try and create a new Global.asax file, the option to create a code behind file is greyed out.
Why isn't my Global.Asax.cs code being executed?
private void Application_Start(object sender, EventArgs e)
{
int x = 1;
int y = 1;
int z=1/(x-y)
}

In a button click, I need to be able to hide my ModalPanel and then continue running other code server-side. I currently have it this way:
[Code]....
It hides the panel at the of the event handler because that's when the page posts back. So what can I do to hide the panel and then continue running the rest of the server-side code?
Basically what I'm trying to do is the following:
1. Button_display in my webform simply displays my UpdatePanel via ModalPopupExtender.
2. Button_closePanel_Click will hide my UpdatePanel and then run some server-side code, which would display my UpdateProgress control.
protected void Button_closePanel_Click(object sender, EventArgs e)
