How to Create a Generic Method to Get the Enum Description in C#

        public static SelectList GetSelectListForEnumWithDescription(Type enumType)
        {
            var list = new List<Object>();
            Array enumValues = Enum.GetValues(enumType);
         
            foreach (Enum enumValue in enumValues)
            {
                list.Add(new
                              {
                                 ID = (int)Enum.Parse(enumType, enumValue.ToString()),
                                 Value = GetEnumDescription(enumValue)});
                               }
              return new SelectList(list, "ID", "Value");
        }

        public static string GetEnumDescription(Enum value)
        {

            FieldInfo fi = value.GetType().GetField(value.ToString());

            DescriptionAttribute[] attributes =
                (DescriptionAttribute[]) fi.GetCustomAttributes(typeof (DescriptionAttribute), false);

            if (attributes != null && attributes.Length > 0)

                return attributes[0].Description;

            else return value.ToString();

How to open a new tab On click of a hyper-linked column in Telerik Razor Grid

Today i got a requirement to open a external URL in a tab when the linked column is clicked.
This  can be achieved by simply adding the client template/ template to the linked column.

1) Using Template Attribute in the Telerik Grid

column.Bound(a => a.Website)
      .Template(@<text><a href="@Url.Content(item.Website)" target="_blank">@item.Website</a></text>)
      .HeaderTemplate(
        @<text>
    <a href="javascript:void(0)" class="t-link" orderby="Website">Website</a>
@Html.TextBoxFor(m => m.Filter.Website)         
</text>);

2) Using Client Template Attribute in the Telerik Grid

column.Bound(a => a.Website)
    .ClientTemplate("<a href='<#= Website #>' target='_blank'><#= Website #></a>")
    .HeaderTemplate(
        @<text>
    <a href="javascript:void(0)" class="t-link" orderby="Website">Website</a>
@Html.TextBoxFor(m => m.Filter.Website)         
</text>);

Output:

But the really annoying is that when you click the link it is throwing error  as
 "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable"

This is because the IIS is unable to resolve the path.

Solution to the above issue:

The above issue can be fixed by a simple trick, just you need to append the http:// to the website in the client template or in the template attribute. See the code below:

column.Bound(a => a.Website)
      .Template(@<text><a href="@Url.Content("http://"+item.Website)" target="_blank">@item.Website</a></text>)
      .HeaderTemplate(
        @<text>
    <a href="javascript:void(0)" class="t-link" orderby="Website">Website</a>
@Html.TextBoxFor(m => m.Filter.Website)         
</text>);

Note: Similarly if it is a mail ID column then, use mailto: as the prefix.

Thats it, Enjoy!

How to show the Pager in Telerik Grid both in top and bottom.

While working in a project , my client wants to show the paging in the grid in both in the top of the grid as well as in the bottom of the grid also. As I am using the Telerik grid, it has a property to set while creating the grid. 

So here is the code for it:

.Pageable(p =>
      {
         p.Style(GridPagerStyles.NextPreviousAndNumeric | GridPagerStyles.PageSizeDropDown);    
         p.Position(GridPagerPosition.Both); // this line will do the Magic
         p.PageSize(int.Parse(ViewBag.PageSize ?? "50"), new[] { 10, 20, 50 });
       }).Sortable()

How to Insert space before capital letters using Jquery

Assume you have a string "HelloWorld" and you need to show as "Hello World". How you can achieve it using Jquery.

It can be done in a very simpler way as below:

"Your string".replace( /([a-z])([A-Z])/g, "$1 $2")

so here it will be "HelloWorld".replace( /([a-z])([A-Z])/g, "$1 $2") will produce "Hello World"

Enjoy!

Differentiate between 'All' and 'Any' Operators in LINQ.

In LINQ, All operator is  to check whether all the elements met the specific condition or not. While Any operator checks whether there is any element exist in the collection or not.


For Example:

int array={1,2,3,4,5};

bool result=array.All(i=>i < 6); here it will check the elements and returns true.

Similarly,

bool result= array.Any( ); // here it checks whether the collection has any elements and returns true.


Hope you Enjoyed!

Compile Time View Checking In Asp.net MVC

You might have noticed that in MVC3/MVC4 if you had done some thing wrong in the view files it will not throw any error during compilation and it will build successfully. The error in the file is only noticed during executing/rendering the view file. So in order to trap the error during the compilation time you can follow the method below:

Step-1 :
Open your solution project file in any XML Editor or in the Visual Studio itself  and you will find a tag named
<MVCBuildViews>, here it false and just make it true and save it.

<MVCBuildViews>false</MVCBuildViews>  
 change it to 
<MVCBuildViews>true</MVCBuildViews>


Thats all, so now when your view has any error then it will throw error during the compilation.

The Use of ALL Operator in LINQ

Today, I came across the All operator in LINQ. This operator returns bool value rather than records after condition is satisfied. The operator will be highly helpful when you need some kind of validation to find unique data. for e.g. Checking the existing email  or UserID registered and so on.


Lets Go with a Example to do the Task:

int [] array = { 1,2,3,4,5 };

bool result = array.All(value => value > 2 );

Console.WriteLine(result);  // Here it will print False since it will check all the values and                                         // all the values must be grater than 2.


 result = array.All(value => value < 6 );
Console.WriteLine(result); // Here it will print True since it will check all the values and                                          // found all values are less than 6.


Hope it helps you!
