How to Prevent Blank Page/white space when a Rectangle is hidden in RDLC

Hi All,
   I had a requirement where in I want to hide Rectangle (which had tablix and charts inside it) to show and hide based on query string parameters. The requirement was working fine when it is showing the Rectangle but when the rectangle is hiding it is generating Blank Page.

I searched a lot for a solution and came to know one trick which i would like to share with you .

I took a  new Table(Tablix) . 
Select the Row of the tablix and apply the same visibility expression on the Row visibility that I have applied on Rectangle .
Now drag the rectangle inside the Table row cell , in which you have applied expression .Thats it...!!!
Now check , it will not render Blank page / white space any more... :-)


Point to Note : One thing that only I have noticed and would like to tell you..First apply the Row visibility Expression and then only drag the Rectangle inside the Row cell of the table. This is because , I wasn't able to select the row , if you dragged the Rectangle first.. If you try to select Row, Rectangle gets selected....



Hope it helps!!!

Thanks ,

Convert input string to Title case in C#

Hi All,
   
     This post is about how to convert your input string into TITLE case in C#.

First , let me tell you what is title case : 

When writing a name or a title, it is a common convention to only use capital letters to start the principal words. This is called Title Case. When using Title Case, do not use capital letters for prepositions, articles or conjunctions unless one is the first word.

Examples:

• Snow White and the Seven Dwarfs.
• Newcastle upon Tyne / Brighton on Sea .
• The DiMaggio Line .
• The Last of the Mohicans .

You can convert your input string either in C# code  or in SQL function (scalar function) :

Convert to Title case in C# : 

  public static String TitleCaseString(String s)

        {

            if (s == null) return s;

            String[] words = s.Split(' ');

            for (int i = 0; i < words.Length; i++)

            {

                if (words[i].Length == 0) continue;

                Char firstChar = Char.ToUpper(words[i][0]);

                String rest = "";

                if (words[i].Length > 1)

                {

                    rest = words[i].Substring(1).ToLower();

                }

                words[i] = firstChar + rest;

            }

            return String.Join(" ", words);

        }

Convert to Title case in SQL Server function :

CREATE FUNCTION udf_TitleCase (@InputString VARCHAR(4000) ) 

 RETURNS VARCHAR(4000) 

 AS 

 BEGIN 

 DECLARE @Index INT 

 DECLARE @Char CHAR(1) 

 DECLARE @OutputString VARCHAR(255) 

 SET @OutputString = LOWER(@InputString) 

 SET @Index = 2 

 SET @OutputString = 

 STUFF(@OutputString, 1, 1,UPPER(SUBSTRING(@InputString,1,1))) 

 WHILE @Index <= LEN(@InputString) 

 BEGIN 

 SET @Char = SUBSTRING(@InputString, @Index, 1) 

 IF @Char IN (' ', ';', ':', '!', '?', ',', '.', '_', '-', '/', '&','''','(') 

 IF @Index + 1 <= LEN(@InputString) 

 BEGIN 

 IF @Char != '''' 

 OR 

 UPPER(SUBSTRING(@InputString, @Index + 1, 1)) != 'S' 

 SET @OutputString = 

 STUFF(@OutputString, @Index + 1, 1,UPPER(SUBSTRING(@InputString, @Index + 1, 1))) 

 END 

 SET @Index = @Index + 1 

 END 

 RETURN ISNULL(@OutputString,'') 

 END

   Hope this will help!!

Make RDLC reports as alternate row color

Hi friends,
  Today I will let you know how to make the RDLC rows as alternate colors.
  Just select the row of the report in Design and press F4 , now you can see the properties.
  In the BackgroundColor , click on the Expression hyperlink and write the below expression :

 
=iif(RowNumber(
Nothing) mod 2, "LightBlue", "LightCyan")

Thats it.. you can change the color as you need. I have taken as LightBlue and LightCyan as an example.

Thanks,

How to find 2nd,3rd,4th ..... nth largest / smallest salary in a table

Hi All ,
   Just thought to share with you some simple SQL query that is used very frequently in our projects and mostly asked in interviews as well.
It is " Write a SQL Query to find the 2nd, 3rd, 4th ...........nth largest salary from a table".

Note  here N , N is equal to which largest salary you want to find. Like if you want to find 2nd highest , it will be Top 1 , if you want to find 3rd highest it will be Top 2 , if you want to find 4th highest it will be Top 3 and so on........

So Here is the SQL Query to find out the 3rd largest query from a table :

Similarly if you want to find the smallest salary , the above will remain same except you have to replace :

1)MAX(Salary) with MIN(Salary)  

2) Order by Salary Desc with Order by Salary Asc

Here's the query to find the 2nd smallest salary from the table ...
