                {
                    System.Web.UI.WebControls.TextBox combobox = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[0].FindControl("combo");
                    System.Web.UI.WebControls.TextBox sizes = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[1].FindControl("sizes");
                    System.Web.UI.WebControls.TextBox barcodenumber = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[2].FindControl("barcodeno");
                    System.Web.UI.WebControls.TextBox ratio = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[3].FindControl("ratio");
                    System.Web.UI.WebControls.TextBox qty = (System.Web.UI.WebControls.TextBox)gvmonoprixmasters.Rows[rowIndex].Cells[4].FindControl("qty");
                    combobox.Text = dt.Tables[1].Rows[i - 1]["Combo1"].ToString();
                    sizes.Text = dt.Tables[1].Rows[i - 1]["Sizes"].ToString();
                    barcodenumber.Text = dt.Tables[1].Rows[i - 1]["Barcode_Number"].ToString();
                    ratio.Text = dt.Tables[1].Rows[i - 1]["Ratio"].ToString();
                    qty.Text = dt.Tables[1].Rows[i - 1]["Quantity"].ToString();
                    rowIndex++;
                }

I get all the values when the loop executes 1st time(rowIndex=0) and throws error index was out of range though I increment the rowIndex. dt.Rows.Count=3.

I guess I identified the problem. Initially in pageload, I bind the gridview to have 1 row with textbox for each columns in default. Since the rowcount returns 3, there is only one row present in gridview. So, code according to it...

Hi,
Howmany rows your gridview has?

In pageload, default I loaded gridview with 1 row. Then retrieved from DB, it returns 3. So gridview mismatched with rows I guess

I solved myself ... Its working fine now...

C#

protected void LoadGridViewfromDB()
    {
        try
        {
            DataTable dtCurrentTable =(DataTable)ViewState["CurrentTable"];
            if (ViewState["CurrentTable"] != null)
            {
                DataTable dt = new DataTable();
                DataRow dr = null;
                
                    dt.Columns.Add(new DataColumn("Col1", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col2", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col3", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col4", typeof(string)));
                    dt.Columns.Add(new DataColumn("Col5", typeof(string)));
                    for (int i = 1; i <= dtCurrentTable.Rows.Count; i++)
                    {
                    dr = dt.NewRow();
                    dr["Col1"] = string.Empty;
                    dr["Col2"] = string.Empty;
                    dr["Col3"] = string.Empty;
                    dr["Col4"] = string.Empty;
                    dr["Col5"] = string.Empty;
                    dt.Rows.Add(dr);
                }
                ViewState["CurrentTable"] = dt;
                gvmonoprixmasters.DataSource = dt;
                gvmonoprixmasters.DataBind();
            }
            else
            {
                Response.Write("ViewState is null");
            }
        }
        catch (Exception ee) { }
    }
