curd operation in gridView using ajax

Here we will learn how to do crud operations select,insert, edit, update and delete in grid view using AJAX stored procedure
in asp.net , in asp.net gridview curd operation happen without postback using updatepanel .
Here we will learn curd operation in gridview using stored procedure in asp.net .
Before implement this application first we will design the database table name is 'CollageInfo' and then stored Procedure name is CurdOperationInGridView.
Create Database Table and Stored procedure like following if you needed

CREATE TABLE CollageInfo
(
Collageid int identity  PRIMARY KEY ,
Collagename nvarchar(50),
CollageRank double
)
GO

CREATE PROCEDURE CrudOperationsInGridView
@Collageid int = 0,
@Collagename varchar(50)=null,
@CollageRank int=0,
@status varchar(50)
AS
BEGIN
SET NOCOUNT ON;
--- Insert New Records For GridView
IF @status='INSERT'
BEGIN
INSERT INTO CollageInfo(Collagename,CollageRank) VALUES(@Collagename,@CollageRank)
END
--- Select Records in Table For GridView
IF @status='SELECT'
BEGIN
SELECT Collageid,Collagename,CollageRank FROM CollageInfo
END
--- Update Records in Table  For GridView
IF @status='UPDATE'
BEGIN
UPDATE CollageInfo SET @Collagename=@Collagename,CollageRank=@CollageRank WHERE Collageid=@Collageid
END
--- Delete Records from Table For GridView
IF @status='DELETE'
BEGIN
DELETE FROM CollageInfo where Collageid=@Collageid
END
SET NOCOUNT OFF
END


Once we Create stored procedure in database then add an aspx page and write the following code on .aspx Page.




<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
    <title>GridView Crud  Operations using Stored Procedure in ASP.Net</title>

                            <asp:TemplateField HeaderText="Collage Name">

                            <asp:TemplateField HeaderText="Collage Rank">

                </Triggers>
            </asp:UpdatePanel>
        </div>
    </form>
</body>
</html>

After completion code for .aspx page write the following code on .aspx.cs page


protected void Page_Load(object sender, EventArgs e)
        {
            if (!IsPostBack)
            {
                BindGridview();
            }

                    gvDetailsForCurdOperation.Rows[0].Cells[0].ColumnSpan = columncount;
                    gvDetailsForCurdOperation.Rows[0].Cells[0].Text = "No Records Found";
                }
            }
        }

        protected void gvDetailsForCurdOperation_RowCommand(object sender, GridViewCommandEventArgs e)
        {
            if (e.CommandName.Equals("AddNew"))

            }
        }

        protected void gvDetailsForCurdOperation_RowEditing(object sender, GridViewEditEventArgs e)
        {
            gvDetailsForCurdOperation.EditIndex = e.NewEditIndex;
            BindGridview();
        }

        protected void gvDetailsForCurdOperation_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
        {
            gvDetailsForCurdOperation.EditIndex = -1;
            BindGridview();

        }

        protected void crudoperationsForGrid(string status, string Collagename, string price, int Collageid)
        {
            using (SqlConnection con = new SqlConnection("Data Source=Munesh;Integrated Security=true;Initial Catalog=GridCurdOperation"))
            {
                con.Open();
                SqlCommand cmd = new SqlCommand("CrudOperationsInGridView", con);
                cmd.CommandType = CommandType.StoredProcedure;
                if (status == "INSERT")
                {
                    cmd.Parameters.AddWithValue("@status", status);
                    cmd.Parameters.AddWithValue("@Collagename", Collagename);
                    cmd.Parameters.AddWithValue("@CollageRank", price);
                }
                else if (status == "UPDATE")
                {
                    cmd.Parameters.AddWithValue("@status", status);
                    cmd.Parameters.AddWithValue("@Collagename", Collagename);

                    cmd.Parameters.AddWithValue("@Collageid", Collageid);
                }
                else if (status == "DELETE")
                {
                    cmd.Parameters.AddWithValue("@status", status);
                    cmd.Parameters.AddWithValue("@Collageid", Collageid);
                }
                cmd.ExecuteNonQuery();
                lblresult.ForeColor = Color.Green;
                lblresult.Text = Collagename + " details " + status.ToLower() + "d successfully";
                gvDetailsForCurdOperation.EditIndex = -1;
                BindGridview();
            }
        }

Now  run your application and see the output and perform Curd operation For Gridview.
