Easily Add a Ribbon Into a WinForms Application (C#)

What is the difference between Finalize() and Dispose()

Finalize () is called by Garbage Collector implicitly to free unmanaged resources. The garbage collector calls this method at some point after there are no longer valid references to the object. There are some resources like windows handles, database connections which cannot be collected by the garbage collector. Therefore the programmer needs to call Dispose() method of IDisposable interface.
Dispose () of IDisposable interface is called by the programmer to explicitly release resources when they are no longer being used. Dispose () can be called even if other references to the object are alive. 

Griview Sorting with Bound Fields in C#.Net

declare static variable before page load event

statis int nSort =0;

write below code in gridview sorting event

protected void gvSearch_Sorting(object sender, GridViewSortEventArgs e)
    {
        try
        {
                //sorting Grid For all Records
                DataTable dt = dsFG.Tables[0];---------&gt;fill dataset or datatable from database
                DataView dv = new DataView(dt);
                if (nSort % 2 == 0)
                {
                    dv.Sort = e.SortExpression + " " + "ASC";
                }
                else
                {
                    dv.Sort = e.SortExpression + " " + "DESC";
                }
                nSort++;
                gvSearch.DataSource = dv;
                gvSearch.DataBind();        
        }
        catch (Exception ex)
        {
            lblmessage.Text = ex.Message;
        }
        finally
        {
        }
    }

Passing Data Between Forms in windows Application

In First webform button click event

private void button1_Click(object sender, EventArgs e)
{
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();    }

In second webform 

public Form2(string qs)
    {
        InitializeComponent();
        textBox1.Text = qs;

    }

Passing Data Between Forms in windows Application

private void button1_Click(object sender, EventArgs e)
{
        Form2 frm2 = new Form2(textBox1.Text);
        frm2.Show();    }

Difference between Convert.ToString() VS .ToString() method

Convert.ToString  handles null and not throws ObjectReferenceNullException. ToString does not handles the null value and throws the null exception error message.

Example:--

    public String FullName = null;

    protected void Page_Load(object sender, EventArgs e)

    {

        try

        {

            Response.Write("<b>.ToString</b><br>");

            Response.Write("FullName :" + FullName.ToString());

        }

        catch (Exception ex)

        {

            Response.Write(ex.Message);

        }

        Response.Write("<br><br>");

        try

        {

            Response.Write("<b>Convert.ToString</b><br>");

            Response.Write("FullName :" + Convert.ToString(FullName));

        }

        catch (Exception ex)

        {

            Response.Write(ex.Message);

        }

    }

Sql Union And UnionAll Operators

The SQL UNION operator combines two or more SELECT statements.

---

The SQL UNION Operator

The UNION operator is used to combine the result-set of two or more SELECT statements.

Notice that each SELECT statement within the UNION must have the same number of columns. The columns must also have similar data types. Also, the columns in each SELECT statement must be in the same order.

SQL UNION Syntax

SELECT column_name(s) FROM table_name1
UNION
SELECT column_name(s) FROM table_name2

Note: The UNION operator selects only distinct values by default. To allow duplicate values, use UNION ALL.

SQL UNION ALL Syntax

SELECT column_name(s) FROM table_name1
UNION ALL
SELECT column_name(s) FROM table_name2

PS: The column names in the result-set of a UNION are always equal to the column names in the first SELECT statement in the UNION.

---

SQL UNION Example

Look at the following tables:

"Employees_Norway":

E_ID	E_Name
01	Hansen, Ola
02	Svendson, Tove
03	Svendson, Stephen
04	Pettersen, Kari

"Employees_USA":

E_ID	E_Name
01	Turner, Sally
02	Kent, Clark
03	Svendson, Stephen
04	Scott, Stephen

Now we want to list all the different employees in Norway and USA.

We use the following SELECT statement:

SELECT E_Name FROM Employees_Norway
UNION
SELECT E_Name FROM Employees_USA

The result-set will look like this:

E_Name
Hansen, Ola
Svendson, Tove
Svendson, Stephen
Pettersen, Kari
Turner, Sally
Kent, Clark
Scott, Stephen

Note: This command cannot be used to list all employees in Norway and USA. In the example above we have two employees with equal names, and only one of them will be listed. The UNION command selects only distinct values.

---

SQL UNION ALL Example

Now we want to list all employees in Norway and USA:

SELECT E_Name FROM Employees_Norway
UNION ALL
SELECT E_Name FROM Employees_USA

Result

E_Name
Hansen, Ola
Svendson, Tove
Svendson, Stephen
Pettersen, Kari
Turner, Sally
Kent, Clark
Svendson, Stephen
Scott, Stephen
