If u are Entering Values in GridView Cells.

Handle Datagridview1_CellValueChanged Event

Exa: 
private void dgrid_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
     if(e.RowIndex>=0)
     {
        if(!string.IsnullOrEmpty(dgrid.Rows[e.RowIndex].Cells["quantity"].Value.ToString()) && !string.IsnullOrEmpty(dgrid.Rows[e.RowIndex].Cells["Price"].Value.ToString())
            {
               dgrid.Rows[e.RowIndex].Cells["commonPrice"].Value = Convert.ToDouble(dgrid.Rows[e.RowIndex].Cells["quantity"].Value) *
Convert.ToDouble(dgrid.Rows[e.RowIndex].Cells["Price"].Value)
                //Ensure That Quantity and Price Should be Digits Only.  
            }
     }
}
vote if it is useful one.

Hi Lester,

First you get the Price value into DataTable and then to use the following Code

dtData --> DataTable Object

dtData.Columns.Add("CommonPrice");

for(int ix=0;ix<dtData.Rows.Count;ix++)
{
   dtData.Rows[ix]["CommonPrice"]=((decimal.Parse(dtData.Rows[ix]["Price"]))*(int.Parse(TextBox1.Text))).ToString();
}

DataGridView1.DataSource=dtData.Copy();

Try this code.

Cheers :)

Solution 2

See here[^]. Notice how this is done using a bound column in this case.
This can also be achieved using an unbound column.

try to use this

convert the column to Template then do like this

<br />
<asp:label id="lblSubTotatl" runat="server" text='<%# (decimal)Eval("Price")*(decimal)Eval("quantity")%>' > <br />
<br />
<br />
