I want following:

How to set different Width on this cells(controls)?

This is my code:

Table myTbl = new Table();
TableRow tRow1 = new TableRow();

    //Row1 Cells Controls

            TextBox txt11 = new TextBox();
            txt11.ID = "txtDest11";
            txt11.Height = 19;
           //txt11.Width = Unit.Percentage(40);

            TextBox txt12 = new TextBox();
            txt12.ID = "txtKmInCity12";
            txt12.Height = 19;

            TextBox txt13 = new TextBox();
            txt13.ID = "txtKmOutCity13";
            txt13.Height = 19;

            DateTimeControl dt11 = new DateTimeControl();
            dt11.DateOnly = true;
            dt11.ShowWeekNumber = true;
            dt11.LocaleId = 1026;

            DateTimeControl dt12 = new DateTimeControl();
            dt12.DateOnly = true;
            dt12.ShowWeekNumber = true;
            dt12.LocaleId = 1026;

            tRow1 = new TableRow();
            tRow1.Visible = true;

            TableCell tCellZero = new TableCell();
            tCellZero.Controls.Add(rowNo);
            tRow1.Cells.Add(tCellZero);

            TableCell tCellOne = new TableCell();
            tCellOne.Controls.Add(txt11);
            tRow1.Cells.Add(tCellOne);

            TableCell tCellTwo = new TableCell();
            tCellTwo.Controls.Add(dt11);
            tRow1.Cells.Add(tCellTwo);

            TableCell tCellThree = new TableCell();
            tCellThree.Controls.Add(dt12);
            tRow1.Cells.Add(tCellThree);

            TableCell tCellFour = new TableCell();
            tCellFour.Controls.Add(txt12);
            tRow1.Cells.Add(tCellFour);

            TableCell tCellFive = new TableCell();
            tCellFive.Controls.Add(txt13);
            tRow1.Cells.Add(tCellFive);

            myTbl.Rows.Add(tRow1);

Result :

Answer 1

Add width to TableCell instead. Use this:

TableCell myTableCell = new TableCell();
myTableCell.Width = new Unit("25%");

OR

myTableCell.Style.Add("width", "25%");

UPDATE:

For textboxes:

TextBox txt11 = new TextBox();
txt11.ID = "txtDest11";
txt11.Height = 19;
txt11.Style.Add("width", "100%");

For TableCells:

TableCell tCellOne = new TableCell();
 tCellOne.Style.Add("width", "40%");
 tCellOne.Controls.Add(txt11);
 tRow1.Cells.Add(tCellOne);
