Here I am posting my code:

protected void grdItems_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
    lblMsg.Text = string.Empty;
    ItemManagementObject item = new ItemManagementObject();
    ItemManagementDetails Itemdetails = new ItemManagementDetails();
    Status status = new Status();
    InventoryClient objService = new InventoryClient();
    try
    {
        string Id = grdItems.DataKeys[e.RowIndex].Value.ToString();
        GridViewRow row = grdItems.Rows[e.RowIndex];
        //Label id = (Label)row.FindControl("uplbluserid");
        TextBox itemname = (TextBox)row.FindControl("txtItemName");
        DropDownList itemtype = (DropDownList)row.FindControl("ddlItemType");
        TextBox location = (TextBox)row.FindControl("txtLocation");
        TextBox Quantity = (TextBox)row.FindControl("txtQty");
        TextBox UnitCost = (TextBox)row.FindControl("txtUnitCost");
        item.Id = Convert.ToInt32(Id);
        item.StoreId = Convert.ToInt32(ddlStoreId.SelectedValue);
        item.ItemName = itemname.Text;
        item.ItemType = Convert.ToInt32(itemtype.SelectedItem.Value);
        item.Location = location.Text;
        item.Quantity = Convert.ToDecimal(Quantity.Text);
        item.Cost = Convert.ToDecimal(UnitCost.Text);
        status = objService.FillValuesItem(item);
        if (status.CallStatus == true)
        {
    
            if (status.ProcedureStatus == true)
            {
                lblMsg.Text = "Saved Successfully";
    
            }
            else
            {
                lblMsg.Text = "ItemName are already exists";
    
            }
        }
        grdItems.EditIndex = -1;
        BindGrid();
    }
}
