How to specify location of images in aspx page for Sitecore

I was clueless while displaying search image in all the aspx pages and ascx web control of Sitecore. As on some pages I was getting my image but while on some pages I was not missing the image.

I tried different path as below but all was wrong

<img src="../images/search.png" alt="search image" />

<img src="~/images/search.png" alt="search image" />

<img src="images/search.png" alt="search image" />

Correct one is to use path that starts with “/” as it automatically resolve its path as below

<img src="/images/search.png" alt="search image" />

Final note is - Never specify "../" for any image as for any web request IIS resolve it accordingly. So always write root path as "/" + physical image path.

Hope it helps someone in anyway.

How to repeat particular string or char into certain number of times

I was writing a program for showing a tree structure in textbox. I was trying to concatenate tabs and spaces in string. Soon I realize that it’s a very tedious way to achieve the result. I thought that .NET is the Ocean and there must be some way to repeat the particular string or character certain number of times. For example if I have character ‘0’ and I want to display it 5 times on screen. 

How to do it?

FOR and FOR EACH Loops are common, but I need some more smart way do it.

Here are some ways that I found

int count = 5;

string str = "PEACE ";

char c = '0';

Console.WriteLine(String.Empty.PadLeft(count, c));     //Output- 00000

string result = new String(c, count);

Console.WriteLine(result); //Output- 00000

Console.WriteLine(new StringBuilder().Insert(0, str, count).ToString());   //Output- PEACE PEACE PEACE PEACE PEACE

First two only repeat characters while last way is to repeat string. Hope this help someone.

How to include or put or embed curly braces in string.Format in C#

I was writing a HTML style within my repeater from code behind page as below

string s = string.Format("<style>.splashImg{0} { background-image:url({1}  );}</style>", 3, " myimage.jpg");

So that my final output should be like

<style>.splashImg3{ background-image:url(myimage.jpg);} </style>

And OMG I received error “Unrecognized escape sequence”. My first reaction was WTF what’s wrong with this code line. After careful look I come to know that it’s a problem of curly braces “{ }“.

As we are specifying curly braces for placeholder like {0} {1}, compiler is confused with other braces like “splashImg3{“.

So simplest solution is just write double braces for non-placeholder braces like “{{“ as shown in yellow color. So final code looks like

string s = string.Format("<style>.splashImg{0} {{ background-image:url( {1}  );}}</style>", 2, "myimage.jpg");

How to apply workflow to all the items of content tree in Sitecore

Its common scenario that, if you created items first and later on creating workflow then you have to manually apply those workflow on template’s standard values and content items.

If there are few items then it fine to do it  manually. But what if there are hundreds, thousands content item.

Best way is to apply them programmatically.

Here is a code to do it. Just put Home item ID or start item

var FirstItem = Sitecore.Context.Database.GetItem(new ID("{A00A11B6-E6DB-45AB-8B54-636FEC3B5523}")) ;

PrintName(FirstItem , 1);

Rest of the item should be iterate by following recursive function and apply workflow on all the items except folder item.

private Item PrintName(Item mainItem, int icounter)

{

    string f = new string('-', icounter);

    TextBox1.Text += f + mainItem.DisplayName + System.Environment.NewLine;

    try

    {

        if (!mainItem.DisplayName.Equals("Homepage"))

        {

            //Put Workflow ID here

            var workflow = Factory.GetDatabase("master").WorkflowProvider.GetWorkflow("{7E9BC450-18EE-401E-892A-1CEF27BF8D9B}");

            workflow.Start(mainItem);

        }

    }

    catch (Exception)

    {

        TextBox1.Text += "Error " + mainItem.DisplayName + System.Environment.NewLine;

    }

    if (mainItem.HasChildren)

    {

        icounter++;

        foreach (var myInnerItem in mainItem.Children.ToList())

        {

            PrintName(myInnerItem, icounter);

        }

    }

    icounter--;

    return null;

}

How to remove .aspx extension from URL in Sitecore website

Sometimes client requirement is to remove extension like .aspx from their website URL. It’s a good practice as all search engine provide better result without extension.

How to do it in Sitecore with .NET?

Sitecore is smartly provide this facility by changing just one entry in web.config file. If you want to remove extension then keep addAspxExtension="false" from <linkManager defaultProvider="sitecore"> section in web.config file as highlighted below

    <linkManager defaultProvider="sitecore">

      <providers>

        <clear/>

        <add name="sitecore" type="Sitecore.Links.LinkProvider, Sitecore.Kernel" addAspxExtension="false" alwaysIncludeServerUrl="false" encodeNames="true" languageEmbedding="asNeeded" languageLocation="filePath" lowercaseUrls="true" shortenUrls="true" useDisplayName="false"/>

      </providers>

    </linkManager>

Woooowww. No programming required J

Dynamic Binding and Static Binding in Sitecore

You can present you data in Sitecore layouts in two ways by using binding. There are two types of binding technics in Sitecore

·         Dynamic Binding

·         Static Binding

If you are binding anything in placeholder from Sitecore then it’s called Dynamic Binding. Here you need to map placeholder and control from Sitecore Layout details section. For example below 3 placeholders are example of dynamic binding.

<sc:placeholder runat="server" key="HeadSection" />

<sc:placeholder runat="server" key="MidSection" />

<sc:placeholder runat="server" key="TailSection" />

If you are specifying sublayout of controls then its called Static binding. Here you don't need to map placeholder and control from Sitecore Layout details section. For example below 3 placeholders are example of static binding.   

<sc:Sublayout ID="scHeadSection" Path="~/Common/HeadSection.ascx" runat="server" />

<sc:Sublayout ID="scMidSection" Path="~/Common/MidSection.ascx" runat="server" />

<sc:Sublayout ID="scTailSection" Path="~/Common/TailSection.ascx" runat="server" />
