Issue Facing for saving Changes does not permitted

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.
The following actions might require a table to be re-created:

Adding a new column to the middle of the table

Dropping a column

Changing column nullability

Changing the order of the columns

Changing the data type of a column <<<<

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

If yes, goto Menu >> Tools >> Options >> Designers and uncheck “Prevent Saving changes that require table re-creation”

Display data from a TextBox to a GridView without saving the data to the database

You have to persists the data between postbacks,

You have many options here: by Session, ViewState, Cache and some other.

protected void Page_Load(object sender, EventArgs e){    if (Page.IsPostback)    {         dt = Session["data_table"] as DataTable;    }}protected void btnTextDisplay_Click(object sender, EventArgs e){     if (dt == null)     {          dt = new DataTable();          DataColumn dc1 = new DataColumn("Name");          DataColumn dc2 = new DataColumn("City");          dt.Columns.Add(dc1);          dt.Columns.Add(dc2);   
     }     DataRow dr = dt.NewRow();     dr[0] = txtName.Text;     dr[1] = txtCity.Text;     dt.Rows.Add(dr);     gvDisplay.DataSource = dt;     gvDisplay.DataBind();     Session["data_table"] = dt;}

mulltiple datatable ,i want to show all the datatable rows into a single gridview.

DataTable dt1 = ( DataTable)Session["a"];
DataTable dt2 = ( DataTable)Session["b"];

DateSet ds=New DataSet();
ds.Tables.Add(dt1);
ds.Tables.Add(dt2);
GridView1.DataSource=ds;
GridVoew1.DataBind();

Sql Server Query for convert number to words

Sql Server Query
First Create a Table of name Sequence
CREATE TABLE [dbo].[Sequence]
    (
      seq INTEGER NOT NULL UNIQUE,
      word [varchar](25) NOT NULL
    )
INSERT INTO [Sequence] SELECT 0, ''
INSERT INTO [Sequence] SELECT 1, 'One'
INSERT INTO [Sequence] SELECT 2, 'Two'
INSERT INTO [Sequence] SELECT 3, 'Three'
INSERT INTO [Sequence] SELECT 4, 'Four'
INSERT INTO [Sequence] SELECT 5, 'Five'
INSERT INTO [Sequence] SELECT 6, 'Six'
INSERT INTO [Sequence] SELECT 7, 'Seven'
INSERT INTO [Sequence] SELECT 8, 'Eight'
INSERT INTO [Sequence] SELECT 9, 'Nine'
INSERT INTO [Sequence] SELECT 10, 'Ten'
INSERT INTO [Sequence] SELECT 11, 'Eleven'
INSERT INTO [Sequence] SELECT 12, 'Twelve'
INSERT INTO [Sequence] SELECT 13, 'Thirteen'
INSERT INTO [Sequence] SELECT 14, 'Fourteen'
INSERT INTO [Sequence] SELECT 15, 'Fifteen'
INSERT INTO [Sequence] SELECT 16, 'Sixteen'
INSERT INTO [Sequence] SELECT 17, 'Seventeen'
INSERT INTO [Sequence] SELECT 18, 'Eighteen'
INSERT INTO [Sequence] SELECT 19, 'Nineteen'
INSERT INTO [Sequence] SELECT 20, 'Twenty'
INSERT INTO [Sequence] SELECT 30, 'Thirty'
INSERT INTO [Sequence] SELECT 40, 'Forty'
INSERT INTO [Sequence] SELECT 50, 'Fifty'
INSERT INTO [Sequence] SELECT 60, 'Sixty'
INSERT INTO [Sequence] SELECT 70, 'Seventy'
INSERT INTO [Sequence] SELECT 80, 'Eighty'
INSERT INTO [Sequence] SELECT 90, 'Ninty'
