Below steps mention how to create delegate is four process:-

1. Declare a delegate.

Gridview header sorting using C#

In my previous post i explained, how to Search string pattern using sql on SQL i had explained how to Add Image in between Rows of a GridView using C#.
Now in this article i will explain one of the useful feature i.e Gridview Sorting.
you need to set the AllowSorting property as a True. and SortExpression Property of columns to the specific field name from the database.
Lets look at the below sample gridview code.
<asp:GridView ID="gvDetails" runat="server"  onsorting="gvDetails_Sorting" AllowSorting="True">
<asp:TemplateField HeaderText="Your Name" SortExpression="FirstName">

Now for sorting you need to create one public property which store the value of direction in the viewstate and base on that select query get fired.

public GetSortDir direction
    if (ViewState["SortingDir"] == null)
            ViewState["SortingDir"] = GetSortDir.Ascending;
         return (GetSortDir)ViewState["SortingDir"];
       ViewState["SortingDir"] = value;

Now check the gridview directon and base on viewstate it will get set the new direction.

    protected void gvDetails_Sorting(object sender, GridViewSortEventArgs e)
        string sortDirection = string.Empty;
        if (direction == sortDirection.Ascending)
            direction = sortDirection.Descending;
            sortDirection = "Desc";
            direction = sortDirection.Ascending;
            sortDirection = "Asc";
        DataView sortedView = new DataView(BindGridView());
        sortedView.Sort = e.SortExpression + " " + sortDirection;
        gvDetails.DataSource = sortedView;

Here BindGridView() is the function which returns the datatable & it contain the query result.
that's it now check the gridview and click on the header and see the sorting effects get added in your gridview.

Search string pattern using sql

In my previous post i explained, how to Parsing delimited string using sql using  SQL and asp net
Now in this article i will explain how to Search the string pattern on entire string using the sql. some time we wanted to search the specific string along with the position then we can think of this way to retrieve the string.

Below i have created some sample query which will retrieve the string on specific position 

create table #TempSQL(csvtext varchar(2000) not null)
insert #
TempSQL select 'tempa,tempb,tempc,tempd,tempe,tempf,tempg' union select 'temp1,temp,temp3,temp4,temp5,temp6'

       dbo.fnGetCsvPart(csvtext,0,default) as pos0
       ,dbo.fnGetCsvPart(csvtext,2,default) as pos2
       ,dbo.fnGetCsvPart(csvtext,2,1) as Entire_string
from #

Here is the generated output from above query.

pos0                       pos2                          Entire_String
------------------ ------------------------------ ------------------------------
temp1                        temp3                   temp3,temp4,temp5,temp6
tempa                        tempc                   tempc,tempd,tempe,tempf,tempg 

Now create this function

create  function dbo.fnGetCsvPart(@csvtext varchar(2000),@indexPos tinyint, @lastPos bit = 0)
returns varchar(5000)

   declare @ivar int; set @ivar = 0
   while 1 = 1
           if @indexPos = 0
                 if @lastPos = 1 or charindex('_',@csvtext,@ivar +1) = 0
                       return substring(@csvtext,@ivar +1,len(@csvtext)-@ivar +1)
                       return substring(@csvtext,@ivar +1,charindex('_',@csvtext,@ivar +1)-@ivar -1)
          select @indexPos = @indexPos-1, @ivar = charindex('_',@csvtext,@ivar +1)
          if @ivar = 0 break
 return null

You may call that directly on your query. check below  example.

select Isnull(dbo.fnGetCsvPart(Document_Name,2,default),'') as [Request]

Parsing a delimited string in SQL

 Most of the time we required the delimited strings to be added in database. today i come up with some simple solution. which will read the string and specified delimited character and base on that it will divide the string and split it across.

(@String varchar(8000), @Delimiter varchar(10) )
RETURNS @RESULTS TABLE (ID int identity(1,1), Val varchar(50))
DECLARE @Value varchar(100)
WHILE @String is not null
SELECT @Value=CASE WHEN PATINDEX('%'+@Delimiter+'%',@String) >0 THEN LEFT(@String,PATINDEX('%'+@Delimiter+'%',@String)-1) ELSE @String END, @String=CASE WHEN PATINDEX('%'+@Delimiter+'%',@String) >0 THEN SUBSTRING(@String,PATINDEX('%'+@Delimiter+'%',@String)+LEN(@Delimiter),LEN(@String)) ELSE NULL END

You can call this function in your query and it will return the result.(as show in img)

select * from dbo.ParseValues('This;is;a;delimited;string;value',';')

and here is your result..

 Hope this will helps you, Please put your comments or dought to help others.

Jquery copy to clipboard

Hi, after long time right? yea... 

anyways after long time i am decided to get back again on blogger :) and make this blogger active and helpful to others.

today i come up with some tricks on javascript or on jquery . its a Copy to clipboard.
In IE we have direct window option to make the copy to clipboard code event , but if you try to do same with Firefox or other it wont work 

so i thought let add some trick to make the copy thing easy :).

Find my below code and put it in the head section

<script type="text/javascript" src=""> </script>

<script type="text/javascript" src="js/jquery.zclip.js"> </script>

    <script type="text/javascript">
        $(document).ready(function() {
                path: 'js/ZeroClipboard.swf',
                copy: function() { return $('input#dynamic').val(); }


and insert this section on your body part.

<br />
        <a href="#" id="copy-dynamic">Click here to copy the value of this input:</a>
        <input style="width: 300px; margin-left: 15px;" type="text" id="dynamic" value="Insert any text here." onfocus="if(this.value=='Insert any text here.'){this.value=''}" onblur="if(this.value==''){this.value='Insert any text here.'}" />

lets download the swf from GitHubs and put it in your js directory accordingly.

now simple run the application , type the text on the textbox and click on copy button it will copy it in your system just like (Ctrl + C).

Put your comments or suggestion to make this thread active and popular.

<div id="div1Seconds" AutoHide="10" style="background: #ccc; border: solid 1px #333">
<input type="button" value="This Button will be hidden in 10 second.">
