Sir,

I am in a ASP.NET project. I stuck in code piece to fetch GridView cell value into a variable. Data being fetched from database in page load(if !PostBack). then all cell value become null when come to the RowCommand event. why that happening?

Here the code:-

int EmpID = Convert.ToInt32(((GridViewRow)(((LinkButton)e.CommandSource).NamingContainer)).Cells[1].Text);

Hi Bineesh VP:
In general, There are mainly two way of taking the cell value from the gridview
1.Boundfield
2.Templatefield
If you used boundfield/autogenerate columns try the below code:
-----------------------------------------------
string desc = GridView1.SelectedRow.Cells[0].Text
If you used templatefield try the below code:
------------------------------------------------
GridViewRow row = GvBoq_Th01.Rows[e.RowIndex];

desc = ((TextBox)row.FindControl("Txtboqdesc")).Text.ToString().Trim();
Full example in Row command event:
---------------------------------
protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
//Determine the RowIndex of the Row whose Button was clicked.
int rowIndex = Convert.ToInt32(e.CommandArgument);

//Reference the GridView Row.
GridViewRow row = GridView1.Rows[rowIndex];

//Fetch value of Name.
string name = (row.FindControl("txtName") as TextBox).Text;

//Fetch value of Country
string country = GridView1.Rows[rowIndex].Cells[1].Text;
}
Hope the above code will help for your problem,kindly let me know if you still had problem
Thanks

SelectedRow property. 
GridViewRow row = dgCustomer.SelectedRow;

TextBox1.Text = row.Cells[1].Text
