Check / Uncheck All Option in Grid view Using JavaScript

Grid View Coding:

<asp:GridView ID="grid_msprep" runat="server" AutoGenerateColumns="false" SkinID="gridviewSkin">

<Columns>

<asp:TemplateField HeaderText="S.No">

<ItemTemplate>

<%#Container.DataItemIndex +1 %>

ItemTemplate>

asp:TemplateField>

<asp:BoundField HeaderText="Journal" DataField="journal" />

<asp:BoundField DataField="article" HeaderText="Article" />

<asp:BoundField DataField ="volume" HeaderText="Volume" />

<asp:BoundField DataField ="issue" HeaderText="Issue" />                           

<asp:BoundField DataField ="category" HeaderText="Category" />

<asp:TemplateField HeaderText="Select">

<HeaderTemplate>

<asp:CheckBox ID="chkall" runat="server" onclick="checkAll(this,'grid_msprep','6')" Text="Check / UnCheck All" />

HeaderTemplate>

<ItemTemplate>

<asp:CheckBox ID="chkselect" runat="server" />

ItemTemplate>

asp:TemplateField>

Columns>

asp:GridView>

Java Script:

function checkAll(chkValue,gridId,chkBoxColumn)

{  

        var gridview = document.getElementById(gridId);       

        for(var i = 1;i < gridview.rows.length; i++)

        {

                gridview.rows[i].cells[chkBoxColumn].firstChild.checked = chkValue.checked ;           

        }

}

Difference between unique and primary key

Unique and primary key enforces the uniqueness of the column.
Primary key creates with index column and unique key as non-cluster index another main difference is primary key not allowed "Null" Values as well as unique key allows one "Null" only.

Code Review Tools For Dot Net

Code Review Tools:

                As I have found the below two code review tools for .dot net

·         StyleCop

·         FoxCop

Both these tools are freeware edition and this need to be integrated with Dot Net IDE.

How StyleCop Tool Review the Code:

                In default the tool has some validation points for code review. This is would be checked for every code review process.

                We can able to add / delete the code review check list points.

Version Details: Microsoft StyleCop 4.3.3.0 (Dot Net 2005)

C# Rule Settings:

1.       Documentation Rules

2.       Layout Rules

3.       Maintainability Rules

4.       Naming Rules

5.       Ordering Rules

6.       Readability Rules

7.       Spacing Rules

The above rules have the validation points.  Please find the below important validation points

1.       Access Modifier Must Be Declared

2.       Interface Names Must Begin With (I)

3.       Use String Empty For Empty Strings

Standard Naming Conventions

Standard Naming Conventions

The following conventions are being used for naming the Identifiers.

• Pascal casing (The first letter in the identifier and the first letter of each subsequent concatenated word should be capital).

Example: PascalCasing

• Camel casing (The first letter in the identifier is lower case and the first letter of each subsequent concatenated word should be capital).

Example: camelCasing

“c” = camelCase
“P” = PascalCase
“_” = Prefix with _Underscore
“x” = Not Applicable.

Identifier	Public	Protected	Internal	Private	Example
Class or Struct	P	P	P	P	-
Interface	P	P	P	P	IInvoiceWorkflow [ Add "I" with prefix of interface ]
Method	P	P	P	P	IGetWorkflowDetails
Field	C	C	C	_C	Journal,_journal( Private variable declaration )

 

Coding Style for C Sharp

 

1. Never declare more than one Namespce per file.

2. Avoid putting multiple classes in a single file.

3. Always use curly braces for new statements and conditional statements.

4. Always use tab with indention “4”.

5. Segregate interface implementation by using #region statements.

6. Avoid multiple Main() methods in a single assembly.

7. Avoid interface for a single member.

8. Do not omit access modifiers. Explicitly declare all identifiers with the appropriate access modifier instead of allowing default.

9. Use a single space before and after each operator and brackets.

10. Method name should tell what it does. Do not use mis-leading names. If the method name is obvious, there is no need of documentation explaining what the method does.

Example:

Good: 

void GetJournalName ()
{
 // Save the phone number.
}


Not Good: 

void GetData ()
{
 // Save the phone number.
}

11. Use String.Empty instead of “”

If ( name == String.Empty )
{
 // do something
}

Not Good:

If ( name == “” )
{
 // do something
}

12. For sting comparison prepare for String.Compare() statement.

13. Avoid invoking methods within the conditional expression.

14. Avoid evaluating Boolean condition against true or false.

If ( isValid )
{
 // do something
}


Not Good:

If ( isValid == true )
{
 // do something
}

15. Always use validation avoids Exceptions.

16. Include comments using Task-List keyword flags to allow comment-filtering

// TODO: Place Database Code Here
// UNDONE: Removed P\Invoke Call due to errors
// HACK: Temporary fix until able to refactor

17. Exception Handling process,

• Do not use try/catch blocks for flow-control.

• Never declare empty catch block.

• Only use finally block to release resources from a try statement.

• Always use validation to avoid exception.
