Thanks for your Quick reply Aajmot Sk..

This code is not working it shows an error "Object reference not set to an instance of an object"

Here my code..
.aspx

<asp:GridView ID="gridEmployee" Width="100%" runat="server" AutoGenerateColumns="False" OnRowDataBound="gridEmployee_RowDataBound" >

.aspx.cs
GridView gvDetails = View3.FindControl("gridEmployee") as GridView;
gvDetails.Columns.Clear();

//Operand Col
BoundField b5 = new BoundField();
b5.HeaderText = " ";
b5.DataField = "rno";
b5.ItemStyle.Width = 50;
gvDetails.Columns.Add(b5);
BoundField b4 = new BoundField();
b4.HeaderText = "Employee Details";
b4.DataField = "LabelName";
gvDetails.Columns.Add(b4);

TemplateField tf2 = new TemplateField();
tf2.HeaderText = "Value";
tf2.ItemStyle.Width = 250;
gvDetails.Columns.Add(tf2);

BoundField b3 = new BoundField();
b3.HeaderText = "FieldName";
b3.DataField = "FieldName";
b3.Visible = false;
gvDetails.Columns.Add(b3);

BoundField b1 = new BoundField();
b1.HeaderText = "FieldType";
b1.DataField = "FieldType";
b1.Visible = false;
gvDetails.Columns.Add(b1);

BoundField b2 = new BoundField();
b2.HeaderText = "CellType";
b2.DataField = "CellType";
b2.Visible = false;
gvDetails.Columns.Add(b2);

gvDetails.DataSource = dstFormChild.Tables[0];//i got data from Database in this datatable
gvDetails.DataBind();
ViewState["View3"] = dstFormChild.Tables[0];

protected void gridEmployee_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
string FieldName=(e.Row.DataItem as DataRowView).Row["FieldName"].ToString();
string Fieldtype = (e.Row.DataItem as DataRowView).Row["FieldType"].ToString();
string Celltype = (e.Row.DataItem as DataRowView).Row["CellType"].ToString();
string FieldSize = (e.Row.DataItem as DataRowView).Row["FieldSize"].ToString();
if (Celltype == "C")
{
DropDownList drpEmp = new DropDownList();
drpEmp.ID = "drp" + FieldName;
drpEmp.Width = 250;
GrdinsideCombo(drpEmp, FieldName);
e.Row.Cells[2].Controls.Add(drpEmp);
}
else
{
TextBox txtbox = new TextBox();
txtbox.ID = "txt" + FieldName;
txtbox.MaxLength = Convert.ToInt32(FieldSize);
txtbox.CssClass = Fieldtype.ToLower();
txtbox.Width = 250;
if (Fieldtype.ToLower() == "date")
txtbox.CssClass = "date";
e.Row.Cells[2].Controls.Add(txtbox);
}
}
