Check uncheck all checkboxes in grid view using jquery

By

Introduction:                                  

In my previous article I have explained about  Select deselect all checkboxes in grid view using javascript.In this article I am going to explain the same process using jquery.

 

Explanation:

While working with grid view I got a requirement to select and deselect all checkboxes in a grid view in a single click. For this first create a table and insert some sample records in the table. I am binding the gridview through the procedure at the page load. And at the end I have two buttons which is used for select/deselect all checkboxes.

Below is the query to create table and insert some sample records.


--creating table
CREATE TABLE Employee(Eid INT IDENTITY,Empname VARCHAR(50),Designation VARCHAR(50))

--Inserting into table
INSERT INTO Employee values('Kanna','Software developer')
INSERT INTO Employee values('Dasan','Software developer')
INSERT INTO Employee values('Thirumalai','Network engineer')

--procedure for retriving data
CREATE PROC getEmployee
AS
BEGIN
SELECT * FROM Employee
END

After that add your connection string in web.config

 

<add key="mycon" value="data source=GKANNADASAN;uid=sa;pwd=kanna;
Initial Catalog=master;"/>                      

ASPX code is given below.

<div>
    <asp:GridView runat="server" ID="grdEmployee" AutoGenerateColumns="False">
        <Columns>
            <asp:TemplateField>
                <HeaderTemplate>
                    <asp:CheckBox ID="chkSelectAll" runat="server" Text="" onclick="javascript:SelectAllCheckboxes(this);" />
                </HeaderTemplate>
                <ItemTemplate>
                    <asp:CheckBox ID="chkSelectAdd" runat="server" />
                </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField HeaderText="Employee id" DataField="Eid" />
            <asp:BoundField HeaderText="Name" DataField="Empname" />
            <asp:BoundField HeaderText="Designation" DataField="Designation" />
        </Columns>
    </asp:GridView>
</div>

 

After that add the below mentioned namespaces in code behind file.

 

using System.Data.SqlClient;
using System.Data;
using System.Configuration;

Below code is used to bind the grid view.


protected void Page_Load(object sender, EventArgs e)
{
    DataSet ds = new DataSet();
    try
    {
        string constr = ConfigurationManager.AppSettings["mycon"];
        SqlConnection con = new SqlConnection();
        SqlCommand cmd = new SqlCommand();
        con.ConnectionString = constr;
        cmd.Connection = con;
        cmd.CommandText = "getEmployee";
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter sda = new SqlDataAdapter();
        sda.SelectCommand = cmd;
        sda.Fill(ds);
        if (ds.Tables[0] != null)
        {
            grdEmployee.DataSource=ds.Tables[0];
            grdEmployee.DataBind();
        }
    }
    catch (Exception ex)
    {
          
    }
}

 

After that in aspx page I wrote a jquery function for selecting and deselecting checkboxes. The jquery code is given below.


<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"></script>
<script type="text/javascript">

    function SelectAllCheckboxes(chk) {
        $('#<%=gvProductBrow.ClientID %>').find("input:checkbox").each(function () {
            if (this != chk) {
                this.checked = chk.checked;
            }
        });
    }
</script>

Dynamically programmatically add contols at run time Asp.Net

By
Introduction: In my previous article I have explained about What is View State? How to Store and retrieve values from View State . In this article I am going to explain how to add controls programmatically on run time. Explanation: This example adds a text box and button to a Web Forms page at run time. It also dynamically binds an event handler to the button's   Click   event. The handler displays the values of the dynamically generated text box. The controls are added into a   Panel   Web server control, which acts as a placeholder. The controls are separated in the panel with line breaks (HTML <BR> elements), which are added to the panel using the   LiteralControl   control.

C# Extension Methods Example

By
In this article i am going to explain about Extension Methods  with example. Extension methods enable you to "add" methods to existing types without creating a new derived type, recompiling, or otherwise modifying the original type. Extension methods are a special kind of static method, but they are called as if they were instance methods on the extended type. For client code written in C# and Visual Basic, there is no apparent difference between calling an extension method and the methods that are actually defined in a type. If you do implement extension methods for a given type, remember the following points: An extension method will never be called if it has the same signature as a method defined in the type. Extension methods are brought into scope at the namespace level. For example, if you have multiple static classes that contain extension methods in a single namespace named Extensions, they will all be brought into scope by the using Extensions; directive. ...
