.net - Ranking Priority Using DropDownList In C#?
Jan 26, 2011
My idea is to build a Ranking Priority using a DropDownList ASP server control.Here's my setup: I have 3 DropDownLists and it has 3 items ("First", "Second", "Third") on each DropDownLists. When I have chosen the 1st DropDownList assuming the item I have selected is "First" and on the 2nd DropDownList by default its SelectedItem is "First" also the item of the 1st DropDownList on which I have selected must be swapped on the 2nd DropDownList. In short there would be unique SelectedItems on each DropDownList and in every SelectedIndexChanged event occuring there would be swapping of items on the 3 DropDownLists. That's what my Ranking Priority would be.My question would be, how can I swapped a previous item on the DropDownList going from one another DropDownList where I have selected on and placed a new item?Here's my code:
protected void DropDownListPriority_SelectedIndexChanged(object sender, EventArgs e)
{
DropDownList ddlRank = (DropDownList)sender;
[code]...

I have one grid view, similar to a Ranking, a ranking of Players registered on my created game. I added a Select button, "Play" to this grid view, and what i want to do is connect the play button with another player. Dont know if im explaining it all right but, its likeClick "Play", It goes to Ranking Table, Gets the mail of the registered player i want to play, and then i do my function about who wins the interaction.

Given this route:
routes.MapRoute("home", "{action}/{id}",
new { controller = "home", action = "index", id = UrlParameter.Optional });
...and this action:
public ActionResult Hi(string id) {
return Content("hello, id: " + id);
}
Question #1
What is the response for:
[URL]
Question #2
What is the response for:
[URL]
Content-Length: 4
Content-Type: application/x-www-form-urlencoded
id=3
I believe this is a bug and the route value should always have precedence, since the URL is what identifies a resource. If you write a POST, PUT or DELETE action you expect the id coming from the URL, not from the body of the request. This could cause changes to a different resource, and can be exploited by malicious users.
After doing some research found that the issue is the default ValueProviderFactory registration order, where FormValueProviderFactory comes before RouteDataValueProviderFactory. Instead of messing with the order I created a CustomModelBinderAttribute:

I have a dillemma.. or more of a design hump.
I have a web application that allows a number of teams to be assigned placement rankings, thus giving the players on that particular team.. seed points.
I am stuck as to how to use a Gridview to display the Teams, then allow a ranking to be assigned to each team.
(Dont allow more than one number per rank [no two teams can ever tie, or have the same finishing place.

I got a issue with sending mail. The mail itself is made with plain text & html, it goes away good and all. Now the problem is that some get it like plain some get it like html. Like I tried to send one to myself on hotmail, It looked great was the html, seconds later I open it on my phone the same email address and there was the plain one. Some get the plain when looking on a computer to.How can I set priority on the html text instead of the plain? or is there a way?
Second I issue is that I can not send email to some mail's like any address with .pl in it. What could this possibly be? I should say that I do use my own winserver2008 and use the localhost smtp on it.

I have a page with 2 Controls, a ListBox and a DropDownList.
In the DropDownList you can select a PLACE.
In the ListBox you can see all DOCUMENTS for the selected PLACE.
If you select a DOCUMENT, the program does a redirect on the selected DOCUMENT.
So, there are an AutoPostBack and an Event (if you select another Item) on both Controls.
The problem is: If I select a PLACE, then I select a DOCUMENT (the pdf document is opened), and then I go back on the page and I want to select another PLACE, the program doesn't select another PLACE, but opens the old DOCUMENT, because there are 2 Events, one to change the PLACE and one to open the DOCUMENTS.
Can I give a priority at the Events?

I am in doubt about ranking ASP.NET sites in Google, Bing and Yahoo. Is there any considerable worse ranking for ASP.NET sites, than ordinary HTML pages or PHP pages for example? I'm used to develop in ASP.NET, and I have some functionality with database and using charts. So if ASP.NET does not affect to much on ranking, I would stay on that. Is there any advice what to do, or any considerable hints that I must be carefully with ASP.NET when developing, to not hurt ranking?

I am having a problem with disabling DropDownList based on the chice of 1st DropDownList, there is no post back occuring, and it is a template based web app here is the current code:
<script type="text/javascript">
$(function() { var dropDownList1 = $('#<%= ddlUserType.ClientID %>');
var dropDownList2 = $('#<%= ddlMember.ClientID %>'); dropDownList1.change(function(e) {
if ( jQuery("#ddlUserType").val() != "ETOC") dropDownList2.removeAttr('disabled'); e.preventDefault();
else
dropDownList2.removeAttr('enabled'); e.preventDefault(); }
} );
</script>
what is happening now is page is blank and if I remove the above code everything shows, where I am going wrong. here is the plain and final javascript code which worked:
<script language="javascript">
function CheckDropDownState(lstbox)
{
if (lstbox.selectedIndex == 3) { document.forms[0].ddlMember.disabled = 1; }
else { document.forms[0].ddlMember.disabled = 0; }
}
</script>
and thew .aspx code: <asp:dropdownlist id="ddlUserType" runat="server" onclick="CheckDropDownState(this);"></asp:dropdownlist>

I have a gridview with 3 nested dropdownlists in one cell on edit like this:To get the exact fields when the user clicks on edit I used the following code(yes it's messy)
[Code]....
The BLLOnderhoud is a class and the getReserveInfo is used to get the Model - Brand(merk) Information.Since the dropdownlists are nested in the gridview I can't call them directly and they can't call any of my functions.And this is the problem, when I change the dropdownfield Model the Auto field wich is the last dropdown(in the picture is a typo) should be binded like in the following code:
[Code]....
But the dropdownlist onDataBound event can't call any of my functions that are in my class.So my question is how can the onDataBound event of the second dropbox trigger a function? The only thing that the function has to do is to bind the 3rd dropdownlist

I am making an application that deals with vehicles. I need two DropDownLists:
Makes: All Vehicle Makes
Models: Models that belong to the selected value of the Make DropDownList
How is this done in MVC2? My Idea: Do I use an ajax call when my first list is selected and then pull back the Models to bind to the Model DDL? How would model binding come into play that way? UPDATE I posted what I ended up doing as an answer. It is super simple and works great. You can use a get too if you feel so inclined, but you have to specify that you want to like so... return Json(citiesList, JsonRequestBehavior.AllowGet);
