MVC :: Dynamically Adding TextBox And Verifying Value?

Feb 22, 2011

I have following DropDownList entry in partial View.

<%: Html.DropDownListFor(model => model.Category, new SelectList(new[] { "Airport", "Bar", "Club", "Other" }))%>

I want to execute following lines only if user has selected "Other" from dropdownlist. Could you please tell me how to do this?

C# - Dynamically Adding A Textbox To A Panel On Button Click?

Jan 13, 2010

I just don't understand how this is done. I've gone through several questions here and from a few other websites.

Basically, a company will be adding process steps, and I want there to be a textbox with a button next to it that reads "Add another step." Once clicked, a new textbox will appear beneath the current one, and the button will be moved next to the new text box. What do I need to do?

Oct 12, 2010

I am building a user control for other programmers that I work with. It will be used to interface with our Authorize.Net accout. Is there a way in code to verify that the connection is SSL? If it isn't I'm going to disable the code to keep any of our programmers from accidentally trying to use the user control on a page that isn't SSL.

Verifying Binary Content With WatiN?

Dec 14, 2010

I'm testing a site that serves up some binary (i.e. non-HTML) content. Some links directly deliver custom images, other links custom PDF's.

I'm building test cases in WatiN and NUnit. Wondering if there's a way, using WatiN to get it load a page and then get the byte[] contents of that page.

Currently, I'm just launching a WebClient to grab the content, rather than through WatiN but that's more untested code in my test suite.

VS 2013 - Verifying Uploaded File Columns

Nov 20, 2015

It's been requested of me to create an application to allow uploading a text file.

I've created the app using the FileUpload control and then was told that I need to check that there is specific data, in specific columns, to verify that the correct text file was uploaded.

i.e.; date in column 5, a number in column 6, an email address in column 15, etc...

- I used a StreamReader with the saved path of the file as the file to a string variable called sCurrentRow.
- Now, because my file does not have column headings, I had to use 'LastName_tx = Strip(Trim(Mid(sCurrentRow, 3, 25)))'
- I'm using VS 2013

Mvccontrib Test Helper And Verifying Http Post Routes And Parameters?

Jan 29, 2010

In my Asp.net MVC app, I have two methods on a controller, one for when the user first arrives on the view and then one when they submit the form on said view.

public ActionResult Foo() {}
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Foo(string id, Account accountToFoo) {}

In the second action, there's a custom model binder that's assembling the account object that I'm acting on, though that's really not important. This all works fine in testing locally on a server.We try to be pretty good about writing unit tests to test all our different views are properly getting routed to, including those that are HTTP POST. To do so, we've been using mvccontrib's test helper.

Testing gets have been super simple

"~/account/foo/myusername".
Route().
ShouldMapTo<AccountController>(c => c.Foo("myusername"));

My question is in testing POST routes, how do I write the lambda that I would use to verify the post is receiving accurate values, similar to the GET test above?

For a POST, it looks something like:

"~/account/foo".
WithMethod(HttpVerbs.Post).
ShouldMapTo<AccountController>(a => something_something);

It's the something_something portion of my lambda that I'm having trouble with. Using arbitrary values doesn't work ("a => a.Foo(0, new Account()"). How would I specify the expected values as part of the test?EDIT I was hoping there was something akin to the way Moq has lambdas for statements such as foo.Setup(s => s.Foo(It.IsAny(), It.Is(i => i > 32)) and so on. Even I have to explicitly supply the values, that's workable--I just can't seem to grok the desired structure to pass those explicit values.

Web Forms :: Dynamically Adding A Css Class?

Nov 18, 2010

I have a website built that uses master page templates. In the master page I have a simple menu in a list. This is not dynamic (yet!).

I am trying to put together some code behind to write a simple css class to one of the menu links if the Request.ServerVariables("URL") is equal to the current page URL

I have no code written because everything complains when I try to come up with something. I was thinking of doing it using a switch function but am I over complicating things?Below is the simple menu with the class I am trying to write to the link:

<div id="nav">
<ul>
<li><a class="selected" href="Default.aspx" title=""></li>
<li><a href="" title="ThisPage.aspx"></li> [code]....

Dynamic - Dynamically Adding A Commandbutton?

Apr 1, 2011

I have a page with a dynamically created command button. I need to dynamically wire up a click event so I can grab the CommandArgument of the clicked button.

Button b = new Button();
b.ID = "btnTrigger2";
b.CssClass = "hiddenBtn";
b.CommandName = "lbl3";
b.Click += new EventHandler(btnTrigger_Click);

The problem is the last line - I can't wire up an EventHandler this way - I need to use the standard EventArgs instead of CommandEventArgs. There's got to be a way.

EDIT

Figured I'd post the code that finally worked in case anyone else tries to do the same thing.

string tabLoadedScript = string.Empty;
string postBackScript = string.Empty;
string script = " <script language='javascript' type='text/javascript'>" + System.Environment.NewLine;
script += "function clientActiveTabChanged(sender, args) {" + System.Environment.NewLine;
int i = 0;
foreach(TabPanel tp in tc1.Tabs)
{
Button b = new Button();
b.ID = "btn" + tp.ClientID;
b.CssClass = "hiddenBtn";
b.CommandName = tp.ID;
b.Command += btnTrigger_Click;
this.form1.Controls.Add(b);
AsyncPostBackTrigger trg = new AsyncPostBackTrigger();
trg.ControlID = "btn" + tp.ClientID;
tabLoadedScript += "var isTab" + tp.ClientID + "loaded=$get('" + tp.Controls[0].ClientID + "');" + System.Environment.NewLine;
postBackScript += "if(!isTab" + tp.ClientID + "loaded && sender.get_activeTabIndex() == " + i + ") {" + System.Environment.NewLine;
postBackScript += "__doPostBack('" + b.ClientID + "','');}" + System.Environment.NewLine;
i++;
}
script += tabLoadedScript;
script += postBackScript;
script += "}" + System.Environment.NewLine;
script += "</script>";

this.ClientScript.RegisterClientScriptBlock(this.GetType(), "cs", script, false);
protected void btnTrigger_Click(object sender, CommandEventArgs e)
{
System.Threading.Thread.Sleep(2500);
Panel ctrl = (Panel) FindControlRecursive(this, "pnl" + e.CommandName);
ctrl.Visible = true;
}
public static Control FindControlRecursive(Control Root, string Id)
{
if(Root.ID == Id)
return Root;
foreach(Control Ctl in Root.Controls)
{
Control FoundCtl = FindControlRecursive(Ctl, Id);
if(FoundCtl != null)
return FoundCtl;
}
return null;

VS 2008 Adding Columns To A Gridview Dynamically

Jul 13, 2010

I have seen code for adding columns at runtime but here is another scenario for you. I am using a SQLDatasource control for my gridview. And the data returned can have different columns based on the filter meaning one time I may have a column A1, A2, A3 and another time I may have A2, A3, A4. Is there any way I can look at the columns when it is binded at the beginning and add the columns first?

I really need to use the SQLDatasource though because I am connecting to an AS400 and it is using a connection already made in the webconfig and do not know any other way. I do if it was MSSQL server but not this.
