Rather than building your table on page load if postback, build the table in the button click event for your first button.  See if that helps you with being able to modify the cells.

Hi,

Thanks for the info. Can I get some code snippets?? The table would not be exesting when the page first loads. Hence, we can easily handle that in the "IsPostBack" block of the if-coditional in the page_load.

The following is the function I use for creating the table. 'txtRows' and 'txtCols' are two text boxes for getting the number of rows and columns. 'tblDesignArea' is table, 'tr' is table row and 'tc' is table cell.

    // public....
    public TableRow tr;
    public TableCell tc;
    public Table tblDesignArea = new Table();

     protected void createTable()
    {
        if (txtRows.Text != "" && txtCols.Text != "")
        {
            //Add new table rows and columns
            int rows, cols;
            string rowID, cellID;

            for (rows = 1; rows <= Convert.ToInt32(txtRows.Text.ToString()); rows++)
            {
                rowID = "TableRow_" + rows.ToString();
                tr = new TableRow();
                tr.ID = rowID;
                tr.HorizontalAlign = HorizontalAlign.Center;
                tr.VerticalAlign = VerticalAlign.Middle;
                tr.EnableViewState = true;
                tblDesignArea.Rows.Add(tr); //adding row to table...

                for (cols = 1; cols <= Convert.ToInt32(txtCols.Text.ToString()); cols++)
                {
                    cellID = "TableCell_" + rows.ToString() + "_" + cols.ToString();
                    tc = new TableCell();
                    tc.ID = cellID;
                    tc.Height = 25;
                    tc.Width = 125;
                    tc.BorderWidth = 1;
                    tc.BackColor = System.Drawing.Color.White;
                    tc.BorderColor = System.Drawing.Color.LightBlue;
                    tc.ForeColor = System.Drawing.Color.Gray;
                    tc.HorizontalAlign = HorizontalAlign.Center;
                    tc.VerticalAlign = VerticalAlign.Middle;
                    tc.EnableViewState = true;
                   
                    tr.Cells.Add(tc); // adding cell to row.....
                }
            }
        }
        tblDesignArea.EnableViewState = true;
        pnlDesign.Controls.Add(tblDesignArea); // adding table to panel.     
    }  

Let me know how you save the view state and load the view state. I am not sure of what the EnableViewState does....

Neways, do suggest some thing.

Sasmit.
