Yesterday I wrote a post about how to achive a redirect for domain.com to www.domain.com using IIS 6. Today I will show you how easy it is to set this up for IIS 7 on Win Server 2008.

You should be aware that this install requires a reboot. Only install on your server if you are in a position to restart your server.

First thing you need to do is download the rewrite module for IIS 7 from Microsoft. The 32bit version is here and the 64bit version here.

Before you can install this module you need to stop some services running on your server. Open the command prompt (Start -> Run -> type cmd and press enter) and type: net stop was /y

Now double click on the file you just downloaded and install the product. It can take a few mins and look like it's after hanging but give it a moment and it will install for you. You will be prompted to restart your server. Do this now as without a restart IIS will give you a 503 HTTP error when attempting to display a webpage.

Once the server has restarted open IIS Manager and make sure that both your domain and relevant application pool have been restarted.

Open up your browser and test your site just to double check everything is ok after the install. You should find that everything is working as normal.

You can now put the following rule in your web.config file within the <system.webServer> tag:

Save and FTP the web.config file to your server. If you type in yourdomain.com (without www.) you should notice that it redirects you to www.yourdomain.com now.

For more information about rerouting your traffic you can visit the IIS site for more details. A great place to start is on the Rule with Rewrite Map page.

If you have a SSL on your site chances are that you only want your visitors to go through your site on one particular domain. Let's say you own domain.com and you always want your visitors to go to www.domain.com when using your site. IIS 7 has a really cool rewrite module that you can use but IIS 6 users need to jump through some hoops to get this function working.

It might be the first day of December but that hasn't stop us from launching 2 new websites to get our December releases off to a great start! Aquatech Ireland have launched 2 new online stores and a brochure site to open up their products to customers all around the world.

I was recently asked to look into making a JQuery UI dialog box (aka a modal box) work with asp.net. I thought it would be straight forward but as with anything in asp.net it turned out to be a little bit trickier than I had initially thought. Part of the problem was that I wanted to put the dialog box on an asp.net submit button and depending on the user's choice either submit the page or cancel the action.

Thankfully I stumbled across this great article over at DeviantPoint. It was pretty much exactly what I needed. However, for my example I needed to only show the dialog box if any of the checkboxes on the screen were not selected. In other words a normal postback would occur if every check was selected but if there were any checkboxes not selected the user would be asked to confirm their action.

If you take a look at my very basic demo page you will see exactly what I'm talking about. You will find all of the code within the source files I have posted for download but below is a brief overview of what is going on.

            $(function () {
                $("#MsgBox").dialog({
                    autoOpen: false,
                    modal: true,
                    buttons: {
                        "Continue": function () {
                            $(this).dialog("close");
                            eval($("#<%= MsgBoxContinue.ClientID %>").val());
                        },
                        "Cancel": function () {
                            $(this).dialog("close");
                        }
                    }
                });
            });
        });
        function showjQueryDialog() {
            //check to see how many checkboxes there are and how many of those are checked.
            //if any of the checkboxes are not selected then show dialog box.
            var TotalNumCheckboxes = $("#ContentContainer input:checkbox").length;
            var TotalNumCheckboxesChecked = $("#ContentContainer input:checkbox:checked").length;

            if (TotalNumCheckboxes == TotalNumCheckboxesChecked)
            {
                eval($("#<%= MsgBoxContinue.ClientID %>").val());
            }
            else
            {
                $("#MsgBox").dialog("open");
            }
        } 
    
// ]]>

C# Codebehind:

if (!Page.IsPostBack)

        {
            //this line is used to hold the exact postback function call used by the asp.net button
            this.MsgBoxContinue.Value = Page.ClientScript.GetPostBackEventReference(AddToBasket, string.Empty);

            //ensure the postback message is blank on load
            PostBackMsgTest.Text = ""; 
        }

        if (Page.IsPostBack)
        {
            PostBackMsgTest.Text = "Content posted back successfully.";
        }

One of the annoying little things about the asp.net repeater is that if you have text in a <HeaderTemplate> this will be shown on screen even if the repeater is empty. Nine times out of ten you will actually want to hide the text and only show it if the repeater contains information. This can be done by doing the following:

First adjust your repeater so that on PreRender of the repeater you call some code from your code behind:

    
Header text inside my repeater



    
    
        ... show database values in here ...
    

Next on your code behind page put in the following to check if the repeater contains any values:

protected void MyRepeater_PreRender(object sender, System.EventArgs e)

{
   //check to see if the repeater contains any items and if not hide it
   if (MyRepeater.Items.Count == 0)
   {
      MyRepeater.Visible = false;
   }
}

Fire up your page and test the repeater with and without items inside it. You should notice that when the repeater is empty the header text is not displayed which is what we wanted to happen.

I'm just back from a weeklong trip in Kusadasi, Turkey. For anyone thinking about going to Turkey for a sun break I highly recommend it! Below are some top tips to help you get the most out of your stay while in Kusadasi.

If you want to set the default value of a drop down list from a value being passed to you by a third party you should always include a check to ensure that your drop down contains the value so that you don't end up with some nasty compiler errors.

To keep things simple let's say I want to check if my drop down contains the value "MyValue". If it does I want to pre-select that option for the user. To do this I would use something like below:

if (MyDropDownList.Items.FindByValue("MyValue") != null)

{
    MyDropDownList.SelectedValue = "MyValue";
}

You can also search based on the text value of your drop down by using FindByText instead of FindByValue.
